Greetings, fellow travelers in the quantum continuum.
Speaker:I'm Bailey, your disembodied yet charmingly British master
Speaker:of ceremonies here at Impact Quantum, the podcast where
Speaker:qubits aren't just theoretical, an entanglement isn't a
Speaker:relationship status. Today we have an absolute
Speaker:corker of a guest, Bert De Jong. He's not only a
Speaker:senior scientist at Barclay Lab. Yes, that
Speaker:Barclay. But also the director of the Quantum Systems
Speaker:Accelerator, part of the U.S. department of
Speaker:Energy's National Quantum Initiative. Translation.
Speaker:He's the bloke helping push the boundaries of quantum computing
Speaker:and sensing, while the rest of us are still trying to figure out how to
Speaker:update our WI fi Reuters. From gravitational sensing
Speaker:with atoms to real time power grid monitoring, Bert's
Speaker:work is less science fiction and more science faster than you think.
Speaker:So whether you're quantum curious or just quantum confused, you're
Speaker:in for a treat. Now, without further ado, let's
Speaker:beam into the conversation already in progress with hosts Frank La
Speaker:vine and Candace Gilhooly. And the man who makes qubits
Speaker:quiver, Bert De Jong.
Speaker:All right. Hello and welcome back to Impact Quantum, the podcast
Speaker:where we explore the emergent ecosystem and field of quantum
Speaker:computing, where it's not just for physicists anymore, it's
Speaker:also for the quantum curious. And with me, as always, is
Speaker:the most quantum curious person I know, Candace Kahooly. How's it going, Candace?
Speaker:It's great, Frank. Thank you again. I'm very excited about today.
Speaker:Yes, we have an amazing guest here
Speaker:and I'm just looking at his.
Speaker:His LinkedIn about page and it's. It's a lot,
Speaker:so I should ask
Speaker:AI to summarize it, but.
Speaker:But. Welcome to the show. We have Bert De Jong,
Speaker:which hopefully I pronounced that right. He is a driven, strategically thinking
Speaker:leader and team builder, leading with Impact and
Speaker:building next generation leaders. He's a senior scientist at
Speaker:Berkeley Lab and is currently serving as department Head for Computational
Speaker:Sciences and the interim lead for the Applied Computing for
Speaker:Scientific Discovery Group, acsd.
Speaker:ACSD advances scientific computing by developing and enhancing
Speaker:applications in key disciplines, as well as developing
Speaker:tools and libraries for addressing
Speaker:general problems in computational science. Wow. There's a. There's a lot there.
Speaker:So let's. But one of the things here is that you're part of the National
Speaker:Quantum Initiative. Yes.
Speaker:And you're at Berkeley University. The Berkeley University. So
Speaker:that's pretty cool. Continue. Tell
Speaker:us. Tell us what you're up to these days. Yeah,
Speaker:thanks, Frank. Thanks, Candice, for having me. So,
Speaker:yes, to give it a short on the Quantum Side. So I
Speaker:lead large number of programs on the quantum on in quantum
Speaker:at Lawrence Berkeley National Lab. So
Speaker:I'm the director of the Quantum System Accelerator, which is one
Speaker:of the five national Quantum initiative centers funded out of the
Speaker:Department of Energy. And these are large centers.
Speaker:We have about 15 institutions and about
Speaker:450 researchers working closely together to
Speaker:really try and move the field of quantum information science
Speaker:effectively quantum computing and quantum quantum sensing forward
Speaker:because we see the potential for the nation
Speaker:to be a leader in this field and continue to be a leader
Speaker:for the foreseeable future. Interesting. You mentioned
Speaker:quantum sensing and quantum sensing is something that's been kind of
Speaker:off the side of my radar. But when I was at the Quantum Tech USA
Speaker:event, quantum sensing was a very
Speaker:hot topic. What is quantum sensing?
Speaker:Unlike classical sensing, you're just doing
Speaker:sensing with quantum information. And so I'll
Speaker:give you a couple of examples.
Speaker:This is some work that actually came out of our center where
Speaker:we actually use atoms to sense
Speaker:gravity. So that's a good example. Bias
Speaker:is important. Why did we work on it? Well, right now, if
Speaker:you do these kinds of things, you have to use sensors that
Speaker:are kilometers apart. By doing quantum
Speaker:sensing and using the power of entanglement, you
Speaker:can actually make sensors that are going to be millimeters in
Speaker:size, extremely small. Now that changes the game
Speaker:on how you can actually use sensing
Speaker:in many, many different applications. Think right
Speaker:now we have satellites trying to measure gravitational behavior.
Speaker:They get their positions, their GPS is impacted by
Speaker:gravitational behavior. So that's one way you can think of
Speaker:sensing, fundamentally
Speaker:sensing. We're trying to figure out really where we could go with
Speaker:applications. We can of course use
Speaker:quantum sensors to sense what's happening
Speaker:with quantum systems. So we better understand for example, what
Speaker:what happens in biological environments.
Speaker:Those are quantum processes on its own. So can we use sensors,
Speaker:quantum entanglement as a sensor
Speaker:to probe these kinds of systems more accurately? But there is even more
Speaker:creative ideas that are people are starting to think about this. Could we do this
Speaker:on, in a larger scale, could we use quantum sensing to
Speaker:detect if something is broken and goes wrong in an electric grid? It
Speaker:could we get real time feedback. Now those are far fetched ideas, right?
Speaker:Those are not things that are happening right now, but those are some
Speaker:of the applications you can think of when it comes to quantum sensing. So
Speaker:this isn't just about, you know, hey, we want to find an oil deposit or
Speaker:natural gas deposit. That would be a potentially other
Speaker:direction to think. Let's say you're looking for
Speaker:rare earths, for example, critical Materials right now,
Speaker:detecting those in the ground is not trivial,
Speaker:but if you can use a signature,
Speaker:a quantum signature, for example, you might be able to
Speaker:detect deposits. I'm not
Speaker:familiar enough with thinking about this in the oil and gas sense,
Speaker:but. Yeah.
Speaker:So I would say the differences in densities is
Speaker:potentially something that you could use as a way to do
Speaker:some quantum sensing. Interesting. The reason
Speaker:why I mentioned is because I remember hearing, I
Speaker:remember hearing about. The first time I heard about quantum sensing was looking
Speaker:for natural resources, whether it was
Speaker:oil, gas, or various types of minerals.
Speaker:Yes. Which I think would be an interesting, interesting use case. But I like the
Speaker:idea of being able to understand what's happening in the power
Speaker:grid because as we record this today, I don't know if the power is back
Speaker:on in Spain and Portugal. Oh, yeah, I heard about that today.
Speaker:They had no power. Like 50 million people without power.
Speaker:That's crazy. Well, I had not heard that,
Speaker:but that is a major,
Speaker:major issue. And of course, we've seen the blackouts here
Speaker:in California, while we have seen them also
Speaker:in the north and in the east. So being able to
Speaker:respond quicker is always going to be a big challenge. Right. These
Speaker:are large, complex systems and
Speaker:single points of failure are everywhere. Yeah, no, that's
Speaker:a good point. That's a good point. And the other thing was
Speaker:I also heard the term quantum radar, which was
Speaker:another kind of use. So in terms of being able to
Speaker:detect drones, smaller objects flying around,
Speaker:stealth device, stealth aircraft, and things like that. So I think quantum
Speaker:sensing is definitely, I think, going to be one of those fields that,
Speaker:you know, for good or for bad, is going to have a big renaissance
Speaker:one way or the other. It just seems that quantum sensing can touch
Speaker:on so many different things. Right? Yeah. You know, like, we're
Speaker:talking about, you know, you were talking about oil and gas. We're talking about,
Speaker:you know, how you can measure
Speaker:gravity, time, acceleration. Like, there's
Speaker:just so many aspects. Maybe quantum sensing is more of,
Speaker:of a bridge that could be like a bridge
Speaker:technology that could, you know, drive a
Speaker:broader spectrum of quantum technologies
Speaker:because it's effective in all of them. I mean, it's. It seems
Speaker:we've been dying to talk to someone
Speaker:about quantum sensing because it's so vitally
Speaker:important. So now it feels like, you know, we got someone here, you
Speaker:know, like, specifically, are you, what
Speaker:fields are, are you working on in, in the, in the
Speaker:quantum sensing sense? Like, what are you focusing on national
Speaker:security? Are you focusing on medical
Speaker:implications, natural resources? What are you guys looking at?
Speaker:So again, as A center. We really have
Speaker:focused on actually finding ways to harness the entanglement
Speaker:so that we can build the foundations. Yes,
Speaker:the field is progressing, and I would think it probably is
Speaker:one of those markets that. One of those technologies that will be the
Speaker:earliest to market relative to computing
Speaker:or networking, simply because over the last
Speaker:five to 10 years, I would say the last decade, the technology
Speaker:really has moved forward to a point that sensing
Speaker:is not that far out. We know how to
Speaker:entangle photons, we know how to entangle the
Speaker:key pieces and actually then be able to very
Speaker:accurately measure these kind of
Speaker:quantum systems and measure the entanglement that allow us to actually
Speaker:make decisions and actually get insights that
Speaker:we are looking for. So it is
Speaker:early, but more and more industries are
Speaker:especially even computing industries
Speaker:are diversifying, diversifying their portfolio.
Speaker:One of the jokes that I always make is, so,
Speaker:for example, if you make a good qubit, it's a
Speaker:terrible sensor. If you have a terrible qubit bit,
Speaker:they're actually excellent sensors. Oh, because of the
Speaker:noise? Yes. If they're sensitive to noise.
Speaker:Right. If they can detect the smallest amount of
Speaker:noise, then they are good for sensors.
Speaker:That makes sense. Okay. All right. So all this work and
Speaker:the chandeliers and all that stuff that they do to shield it out, you
Speaker:actually kind of want that, in a sense. Yes. You
Speaker:kind of work in two directions. Exactly. Quantum computers want to get
Speaker:rid of the noise and be less and less sensitive to
Speaker:noise, while quantum senses want to be more and more and more sensitive to noise.
Speaker:It's that interesting dichotomy, but it also means
Speaker:that if you start thinking about. For us, we are
Speaker:not just building quantum computers,
Speaker:for example, with atoms, we're
Speaker:also trying to measure them more and more accurately. And so the more
Speaker:accurately measure, the more you get
Speaker:sensitive to noise. Right. The extra little
Speaker:piece of noise that you didn't know about that then
Speaker:makes you also better as a sensor.
Speaker:So it's kind of that even though we are developing
Speaker:technologies for quantum, they have that angle of actually being
Speaker:able to readily used in. In a
Speaker:quantum sensing realm, just in a different way.
Speaker:Interesting. And also as the sensors, I don't know if this is as important, but
Speaker:as the sensors become more sensitive,
Speaker:like you can go smaller and smaller and smaller. I don't know
Speaker:if that's necessarily something that is important
Speaker:to this field, but it makes me think when something is sensitive, everyone
Speaker:likes when things can get smaller and smaller. Well, it has to be. Right.
Speaker:So let's say I can build right now a sensor that
Speaker:takes up a Big room in a building. Now, if you want to
Speaker:have that sensor, for example, on a ship or in a
Speaker:submarine or on
Speaker:a plane, you need to make it. Why you want small? You need to make
Speaker:it taller. Or if you want to put it in space, lighter weight,
Speaker:smaller is good, right? So
Speaker:miniaturization, that's what our. I would say
Speaker:our technology advances have been around. If you look at the first
Speaker:kind of space missions, right, Apollo missions,
Speaker:they had computers that were bytes, not kilobytes,
Speaker:bytes, and they were big, right? Now what
Speaker:we have there, we can do in,
Speaker:oh, not even a pinky. It's just going to be
Speaker:a very small square space. And so
Speaker:miniaturization allows you to scale, but actually
Speaker:more we miniaturize, we more and more get closer
Speaker:to the quantum realm, right? Quantum is at the
Speaker:smallest scale. So the smaller you make things,
Speaker:the closer you get to the quantum realm and you start to deal with the
Speaker:same problems that we are dealing with right now. When it comes to quantum computing
Speaker:or. Quantum centering, sensing the invisible and measuring
Speaker:the immeasurable, it's like, you know, it's
Speaker:Star Trek, right? Like, they pull up a tricorder, which is like a handheld device,
Speaker:and they can tell. They can tell everything from, you know, medical issues
Speaker:to, you know, planetary or cosmic
Speaker:like stuff all in the palm of their hand. And, you know, it's. Right
Speaker:now that's still science fiction, but I mean, I can easily see there being uses
Speaker:for it because, you know, in the TV show, there was always a use for
Speaker:it. So I can imagine, you know,
Speaker:that. Would so think of everybody. Well, not
Speaker:everybody, but a lot of people are wearing watches now, right now, where they
Speaker:detect heartbeat, blood pressure, all of that, even
Speaker:oxygen levels. And so there is.
Speaker:That is also a demonstration of new sensing
Speaker:technologies. And there they're using light.
Speaker:It's also a. Photons are the
Speaker:smallest piece you can deal with. So it's all of
Speaker:that miniaturization and putting together
Speaker:more and more foundational knowledge around
Speaker:how materials behave, how photons, how electrons
Speaker:behave, allow us to miniaturize. And
Speaker:all of those phenomena tend to be quantum.
Speaker:And so the smaller we go, the more we need to actually
Speaker:handle quantum information sciences in general.
Speaker:Interesting. I would also
Speaker:imagine quantum sensing would help in error correction with
Speaker:qubits or no. Am I not thinking right?
Speaker:I would have to think through that. But I don't think
Speaker:the way we are doing quantum error correction right now would be
Speaker:directly a sensing thing. Okay. It's more
Speaker:indirect, but yes. Okay, sorry, Candice.
Speaker:Looks like you had a question. No, no, I was just kind of thinking, you
Speaker:know, you know, in my head again, because we were talking about the watches and
Speaker:the medicine. Just what, you know,
Speaker:it's so the next step of, of what this could do
Speaker:for, for people with everyday health issues that they're
Speaker:monitoring. And I don't know, I, I just, I'm very excited about the
Speaker:medical breakthroughs because I just. You keep on seeing how these everyday
Speaker:devices are now being used by all kinds of people. Like, I think about my
Speaker:mom who was like, was so upset about the cell phone. She's like, I
Speaker:wasn't made for the cell phone, candy. She's like, I, I'm 80 years old. Like,
Speaker:I cannot handle the cell phone. I'm like, you can, mom. Like, I swear you
Speaker:can. And now I watch her take the cell phone and put it to her
Speaker:arm to detect her, like, diabetes, rate her diabetes
Speaker:rating, and then how everything is all interconnected now to help
Speaker:her when it wasn't like that even a couple years ago.
Speaker:And so I'm seeing how, you know, with medical technology, it's going
Speaker:faster and faster. And I can see how, you know, as the world is having
Speaker:issue with natural resources, that's going to go faster and of course, with,
Speaker:with security, you know, national security, that's going to be,
Speaker:you know, one of the biggest ways they're going to want to deal with sensors
Speaker:and stuff. So I think it's such a, an incredibly exciting
Speaker:field to investigate and for people to figure out
Speaker:how they get to be a part of it. Yeah. So I'll give you one
Speaker:early sense. So, you know, we already using
Speaker:quantum in our medical fields. Right. So the
Speaker:MRI, many of us have had MRIs
Speaker:driven by Quantum. It's a quantum
Speaker:technology. I didn't know that, to be honest. That's true. I
Speaker:was thinking functional mri, the magnetic one.
Speaker:Yeah. Interesting. So we're already. So we're already using it.
Speaker:Yep. So then why are you using everywhere?
Speaker:Honestly, quantum is everywhere right now. MRI is one. But
Speaker:the fact that we have light bulbs is definitely also a
Speaker:quantum phenomena, especially the new lights.
Speaker:GPS is driven by atomic clocks. So
Speaker:if we measure atomic systems more accurately,
Speaker:we build better atomic clocks. We have better gps.
Speaker:Think of optical fibers in telecom. We are using
Speaker:photons right now, but could we actually use entangled photons
Speaker:in the future to maybe get better
Speaker:quantum networks? I already mentioned
Speaker:the transistors getting smaller and smaller, needing
Speaker:quantum. So it's there in every
Speaker:way, shape or form. So yes.
Speaker:So it shouldn't be such an argument that's going on, or I should
Speaker:say, lively debate in terms of how many years it's going to
Speaker:take for us to be able to, you know, enjoy,
Speaker:you know, what's going on as more and more breakthroughs are happening.
Speaker:Like, it's already happening. Like on the show we
Speaker:spoke with a lovely lady, Anna White of
Speaker:Hedo Match. They're currently using a quantum algorithm
Speaker:in, in their business. You know, we've spoken to, you know, Quantum Knight,
Speaker:who's already, you know, coming up with national security
Speaker:measures that are working with, with quantum and,
Speaker:and quotes, quantum encryption. So, like, things
Speaker:are already happening. We don't have to necessarily
Speaker:wait five or 10 years. It's just going to continue to see the
Speaker:evolution as more funding is put behind the science.
Speaker:Yes, now we are definitely progressing. But so when
Speaker:it looks, when you look at where we are and how we've evolved
Speaker:in the last five, I would say 10 years, we are really
Speaker:trying to push what, what I coined as kind of
Speaker:the second quantum revolution. And yes,
Speaker:census is one. Networking is, is a very
Speaker:different challenge and that's mainly driven by security
Speaker:because, yes, we could potentially break information
Speaker:encryption and then quantum computing. And
Speaker:are they all going to be now? No. Are they
Speaker:all moving forward? Most definitely.
Speaker:And they all have a timeline
Speaker:where, I think depending on how you look at it, I still
Speaker:think quantum computing can have some early impact in the
Speaker:next three to five years. Now, is it
Speaker:going now? I'm sorry, go ahead, go ahead,
Speaker:go ahead. I won't continue your thought. No, it's not
Speaker:like, honestly, in the next five
Speaker:years, a quantum computer probably will not break quantum
Speaker:encryption and break all the,
Speaker:and gets access to all your secret information you might have.
Speaker:But there is going to be a lot of domain areas
Speaker:and a lot of application areas where early
Speaker:demonstrations of quantum computers or
Speaker:even quantum networking will have an impact.
Speaker:We know that banks are actively pursuing
Speaker:their secure networking effectively right now.
Speaker:Surprisingly, not so surprisingly, but it's
Speaker:still interesting. There's a lot of banking companies, for example, that are
Speaker:trying to understand how they can use quantum computing at this point in time.
Speaker:And for them, it's very simple. If you're
Speaker:the first one or you're the fastest when it comes to
Speaker:making decisions on what stocks to trade, for example, you make more money.
Speaker:So everything here in that world is driven
Speaker:by being the fastest. The first,
Speaker:I would say a lot of other technology, a lot of other industries
Speaker:are really looking at, I would say
Speaker:primarily right now, quantum computing as a potential
Speaker:to accelerate their R&D efforts.
Speaker:But that one, as I said, it's going to be very
Speaker:specific areas that. Where that
Speaker:technology, a quantum computing technology will actually help them
Speaker:accelerate their R and D. It's not going to be across
Speaker:all industries, quantum
Speaker:computing, good for certain things. It will not be universal
Speaker:replacement for classical computing in the future.
Speaker:What do you think is some of the biggest. What do you think are the
Speaker:barriers right now? Like, we've talked about the ecosystem, you
Speaker:know, Frank and I discuss this usually with every. Every guest that we've.
Speaker:That we talk about, you know, the ecosystem. Everything from, you know, the
Speaker:physicists and the academics to the commercial,
Speaker:commercial practitioners who are, you know, who are trying to
Speaker:be, you know, the business folk that, that are putting quantum
Speaker:out there to the world and how there is
Speaker:a little. There's a little bit of a chasm between both sides, especially when
Speaker:information is coming out from the commercial side or, you know, because, you
Speaker:know, academia is trying to make sure that everything that's being said
Speaker:is completely true and
Speaker:practical. And sometimes, you know, there's a little bit of a gap between
Speaker:that and there's a little bit of a chasm where I think it'd be better
Speaker:if there was a bridge between the two sides. You know,
Speaker:I'm also of the mentality that I don't want a one, winner take all. I
Speaker:would like there to be like a leader for every type of qubit,
Speaker:you know, that there is another company, because if one company is
Speaker:dedicated to the, you know, ionization, another one is dedicated,
Speaker:you know, to, you know, to the photons or to
Speaker:different qubits, then we could have really some of the best technology
Speaker:possible for everybody. But do you see it
Speaker:as a little bit of a chasm in the ecosystem that there's kind of a
Speaker:little disconnect that's happening between the two sides, or
Speaker:no. Do you think that the two sides are kind of beginning to work with
Speaker:each other? I think the community
Speaker:is getting better and better at working together. I do agree
Speaker:that one of the big challenges that we are right now when it comes to
Speaker:the quantum ecosystem is that there
Speaker:is still a lot of directions quantum
Speaker:information science, or quantum computing can take at this point in time.
Speaker:There is a lot of different platforms that are being developed as we get
Speaker:better and better understanding, better and better control of what
Speaker:qubits can and cannot do. It's
Speaker:not that far and different from where classical
Speaker:computing was for a long time. We had,
Speaker:for a long time, very different technologies. Hey, we move from
Speaker:the abacus to tubes
Speaker:to Effectively transistors. And
Speaker:now there's new types of transistors that are being developed if they
Speaker:want to scale scale smaller and smaller. I don't think we
Speaker:are much further when it comes to the quantum technologies. Right now
Speaker:we have that choice of
Speaker:which technologies will be the best ones. And
Speaker:I think the real question becomes what are these
Speaker:technologies the best for. And I would argue that there
Speaker:is potential that some technologies will be better for certain
Speaker:application areas for certain industries versus others.
Speaker:And again, universal quantum computer,
Speaker:sure we can build one eventually, but is it going
Speaker:to be the best for some of the applications? I don't know.
Speaker:If you look at classical computing right now,
Speaker:we had x86 for the longest time. Now we
Speaker:have GPUs, we have FPGAs, we
Speaker:have new types of technologies that are being developed on the
Speaker:classical computing side too. What you see is a
Speaker:merger from diversity or
Speaker:specialization to universal to back now
Speaker:a diverse set of technologies that is specialized for
Speaker:certain application areas. I would expect
Speaker:that diversity and specialization to
Speaker:be the case for a while when it comes to the quantum technologies. Till
Speaker:we get a couple of that are going to be clear winners. And
Speaker:honestly we have some technologies that are at the forefront right
Speaker:now. There is a lot of dark horses out there still.
Speaker:And so who knows that what we're looking at
Speaker:right now when it comes to quantum technologies. Quantum
Speaker:computing technologies are the ones that are going to be
Speaker:the ones that are going to drive most of the industry.
Speaker:But that matter is top. The matter
Speaker:of quantum information is a complex
Speaker:matter for industry in general to deal
Speaker:with. And so they need to get an early
Speaker:handle on it. Hey, if they have to still use
Speaker:a computer build of tubes to do
Speaker:their work right now and understand how quantum could actually
Speaker:impact their end user
Speaker:application that their domain, so be it.
Speaker:Eventually they will transition like everybody else to the
Speaker:technologies that will be most suited for them for their application
Speaker:area or for their industry. Right, and you mentioned
Speaker:a couple times quantum information science. I think I know what that means,
Speaker:but can you dive deep
Speaker:into that?
Speaker:So pretty much everything that
Speaker:we've talked about so far is part of quantum information
Speaker:sciences. Fundamentally we
Speaker:need to understand and fully grasp what
Speaker:the powers of quantum information, what the power is of
Speaker:quantum. And that umbrella is called quantum information
Speaker:sciences. So this ranges from actually doing
Speaker:understanding the physics to actually doing the engineering,
Speaker:to actually doing things like quantum error correction, doing
Speaker:fundamental computer science theory effectively,
Speaker:which is a lot what quantum error correction is
Speaker:to understand how we can harness a technology,
Speaker:but even fundamentally better understanding what actually
Speaker:Quantum mechanics is how it works.
Speaker:What entanglement actually means, what it
Speaker:means to actually have a statistical process instead of a
Speaker:deterministic process are things that
Speaker:need to be, that are
Speaker:continuously being studied, probed,
Speaker:and better understood. That's the umbrella of
Speaker:quantum information sciences is literally that
Speaker:understanding from the fundamentals to actually getting to a point
Speaker:where we can build systems and engineer
Speaker:systems and then potentially do real
Speaker:applications with them. So this would be kind of, you
Speaker:know, like information
Speaker:theory from Claude Shannon and things like that. Like
Speaker:you go from, you know, this is how you represent
Speaker:information in terms of how do you quantify it, how do you measure it, that
Speaker:sort of thing. Is that that what you mean, but like the quantum version of
Speaker:it? The quantum version of it, yes. Interesting.
Speaker:And that's partly how I guess people were. That's how Shor's algorithm or
Speaker:Grover's algorithm was worked out. Right. Kind of on a whiteboard, so to speak.
Speaker:Yes. And like just working with the theory of it before there was the actual
Speaker:hardware, which, that just boggles my mind. Right, like that you can
Speaker:think this through. So let me ask you this. So
Speaker:I, I, I'm, as you're talking, I'm like doing a little like
Speaker:researching behind the scene here. So they're saying here in, in
Speaker:classical information, imagine a pianist playing one note
Speaker:at a time. Each note is clear and separate, like a classic
Speaker:bit being 0 or 1. But in A, in quantum
Speaker:information, imagine a full orchestra where every instrument
Speaker:plays every note at once, but in perfect
Speaker:harmony. This is like a qubit, which can be
Speaker:a 0 or 1 simultaneously. Superposition. And
Speaker:some instruments are linked, so if one changes, the others
Speaker:can change instantly. Therefore entanglement.
Speaker:That's a very simple,
Speaker:interesting description of doing it. So I would
Speaker:say this is the fun part, of course, then. So
Speaker:you're saying this is like an orchestra, but each instrument playing
Speaker:the right and exact right role. Well, that's what
Speaker:we're trying to get to when it comes to
Speaker:quantum computing or quantum networking. Right now there's a lot of
Speaker:noise in these systems, so
Speaker:some of these instruments might be slightly out of tune.
Speaker:This is why I like. So how do we better tune them
Speaker:and make sure that
Speaker:the high room temperature is not getting them out of tune
Speaker:over time? For example, do you
Speaker:think that the. Fact that you need
Speaker:to get these really isolated systems
Speaker:and down to almost absolute zero, you
Speaker:think that's been a blocker for more of this or is that just,
Speaker:that'll get worked out at some point? That's an
Speaker:engineering problem. I Would say that has been worked out
Speaker:pretty well so far. What we do see is that.
Speaker:So the superconducting qubits, for example, are extremely cold.
Speaker:Actually, the bridges we have
Speaker:that we take superconducting qubits in
Speaker:and then do these quantum processes on with,
Speaker:they're actually colder than the universe. So we're trying
Speaker:to beat what the universe can do to some extent.
Speaker:Right. And so, but we're also seeing this now in the other
Speaker:technologies. So our center, for example, has
Speaker:trapped ions and neutral atoms. Neutral atoms.
Speaker:They're now also going cryo simply because they want
Speaker:to get rid of a lot of the background noise. And,
Speaker:and to do that, cryo is one pair.
Speaker:Cryo means we're just going cold. Right. So.
Speaker:But it's hard, honestly. We can build
Speaker:very good qubits as good as
Speaker:nature will allow them, as long as we don't touch them. Right. So.
Speaker:Right. The best qubits are the ones that we cannot touch.
Speaker:But someone had mentioned that, someone we spoke to talked about
Speaker:if. And then if you touch destroys it. Almost like
Speaker:it, it. It then it does. It doesn't work. And I
Speaker:just was having a hard time kind of conceptually conceptualizing that
Speaker:in my mind about these qubits.
Speaker:Doesn't have to be the case. Right. So a qubit we can build,
Speaker:and if we don't touch it, it probably is staying around for
Speaker:a long time. Now, of course, it's still an environment.
Speaker:Any stray photon, any ray coming out of
Speaker:the cosmos could still impact
Speaker:the system. So perfect isolation still doesn't exist.
Speaker:Now, there is some technologies that people are developing, like topological
Speaker:qubits, where inherently they would be protected against a
Speaker:lot of these background noises. But in the long run,
Speaker:we want to do something with these qubits. We want to operate on
Speaker:them, we want to do something with them
Speaker:to do that. We actually become part of
Speaker:that noise, VR the noise. If we don't do it exact
Speaker:don't rotate the qubit exactly the way we
Speaker:think it does, we introduce noise.
Speaker:If we don't do a sharp enough pulse
Speaker:or we do a slightly different frequency, we are not
Speaker:directly doing what we're thinking we're doing. So we're
Speaker:introducing noise. The other thing is,
Speaker:again, entangling two of these
Speaker:protected or best protected qubits
Speaker:breaks a lot of the symmetries, breaks some of the protection
Speaker:symmetry, for example, so that opens
Speaker:them up again to noise. So the game when it comes to
Speaker:quantum computing is finding a way to
Speaker:control the noise, mitigate the noise to a point.
Speaker:That we can then do quantum error correction on top of
Speaker:that. And reality is, we already doing this in classical
Speaker:computing too. Your memory is error corrected
Speaker:in your computer. Chips have inherent
Speaker:error correction. And how do they do that? They just have
Speaker:multiple versions of it and they just do a majority vote to decide which
Speaker:one is correct. It's not that different. Right now when it comes
Speaker:to quantum error correction, we're doing very similar approaches
Speaker:where you start thinking about how we can do repetition
Speaker:codes effectively. So repeated encoding so that we
Speaker:can kind of decide what is the right answer at some point.
Speaker:Interesting. Yeah.
Speaker:It boggles the mind because you're right. We.
Speaker:I don't really think computer science undergrads today even cover error
Speaker:correction. And I remember my professor when I was
Speaker:in school said, you're probably never going to really see this in the real world.
Speaker:When he was teaching it again.
Speaker:At. The time, his words were something to the effect of this is largely a.
Speaker:Solved problem for classical computing.
Speaker:I think it is a solved problem. It's
Speaker:simple. You can do repetition codes, right? I
Speaker:spent 15 years in high performance
Speaker:computing prior to getting a lot more engaged with
Speaker:quantum, with quantum computing specifically.
Speaker:And we were doing that on the algorithmic side
Speaker:even. It's just replication and being
Speaker:able to make decisions as to when something
Speaker:goes corrupt, if it's corrupt, and how you can
Speaker:correct it at that point in time. And so
Speaker:quantum to some extent has a similar kind
Speaker:of flavor to that right now, where we use
Speaker:inherently things that look like repetition codes, not in
Speaker:a classical sense where we just make five copies of the
Speaker:same thing, but rather store that
Speaker:information in a bunch of qubits and then
Speaker:try to use the entanglement information to
Speaker:decide if a certain qubit is wrong.
Speaker:But fundamentally the ideas are the
Speaker:same. The approach using entanglement and
Speaker:storing information in a different way across
Speaker:qubits allows us to do things that
Speaker:you couldn't do on a classical computer, computer, for example, when it comes to correction.
Speaker:So I would say right now, given what you
Speaker:know and what you do and what's going on in the ecosystem,
Speaker:what is not, I always feel that communication is a
Speaker:problem. You know, those that know, know, and those that don't know
Speaker:don't know what they don't know. And
Speaker:communication can always be better. So what
Speaker:do you think those in the know in quantum could
Speaker:do to be communicating, you know, the
Speaker:importance, the excitement, you know,
Speaker:of what's going on in quantum to get more folks,
Speaker:you know, interested so that, you know,
Speaker:either they want to become knowledgeable themselves or that they're going to make sure that
Speaker:their kids are going to do better in math so that their kids can go
Speaker:into a really, a gigantic array of jobs that
Speaker:don't even exist right now, but are going to exist within, you
Speaker:know, five, 10 years. So what do you think could be
Speaker:done better for communication?
Speaker:Well, that is also a little bit of a twofold thing.
Speaker:So one of the big challenges with a lot of the communication
Speaker:early on had been that it became a hype.
Speaker:And the hype and then not delivering
Speaker:becomes a kind of a
Speaker:failure of death in the long run, it's not going to go anywhere. So
Speaker:communication has to be done in a very balanced way where
Speaker:we need to talk about reality while talking about the
Speaker:excitement and the potentials. But
Speaker:of course, we have a lot of industry right now that, that
Speaker:have a lot of VC capital that need to deliver.
Speaker:And the danger that
Speaker:not just in Quantum, by the way, but also I would say in AI has
Speaker:come across is that there might be sometimes
Speaker:a little bit too much hype. It has gotten a lot better in Quantum. There
Speaker:was a lot more hype, I would say, five years ago than there
Speaker:is now. And that's a big good step.
Speaker:But how to communicate excitement to the right people is
Speaker:a big challenge. And it's something that we have
Speaker:focused also on in our center. We've
Speaker:developed programs to actually try to get the
Speaker:excitement about Quantum for high schoolers
Speaker:looking at going even back to earlier in
Speaker:the K12 ranges because we need to get
Speaker:them excited to go into a STEM field that
Speaker:allows us to get even
Speaker:AA or bachelor's degrees that can
Speaker:build these systems in the future. And you mentioned five to
Speaker:10 years out. No, it's not five to 10 years out, it's
Speaker:now. Companies are building
Speaker:systems, they're installing systems at, at the
Speaker:customers. That's a skill set that doesn't require
Speaker:physicists that are electrical engineers
Speaker:doing the cabling, making sure the fridges are working
Speaker:properly, the network is installed properly,
Speaker:the lasers are aligned properly. That's a very different
Speaker:skill set that companies are looking for right now. And then
Speaker:that's the hardware, but we need software. We need the
Speaker:nice simple interface for the end user.
Speaker:We need software engineers that they don't need to be
Speaker:experts in Quantum, but they need to be able to understand
Speaker:enough so they can build a software infrastructure that is needed to
Speaker:run industrial applications in the future.
Speaker:And the future is sooner. Three to five years
Speaker:for some applications, not forever. And to be clear, we didn't pay you to say
Speaker:that because that's what Candice and I were talking about when we relaunched the show
Speaker:was let's, you know, somebody had said, someone very smart
Speaker:had said something. The effect, there's enough physicists, there's enough
Speaker:theoretical physicists in this field already. What we need are the sales
Speaker:people, we need the marketers, we need every
Speaker:profession that you mentioned and then, then some. Right. It's going to, I think I
Speaker:hate the term it takes a village, but it's going to take a village. It
Speaker:takes a large, large village. And I've seen that, I've visited
Speaker:some companies and it's interesting to see
Speaker:their changing mindset from being
Speaker:physics experiments to starting deliver to deliver
Speaker:early systems to their end users. And it's just
Speaker:a different type of marketing. You need people that can
Speaker:provide support consulting to
Speaker:the less the people that are not as knowledgeable but want to explore
Speaker:these quantum systems for their applications. And then there
Speaker:is a lot of application development that has to be done
Speaker:in the long run. At the end, it's like think
Speaker:of if I want to build a better catalyst,
Speaker:I need to have codes effectively that can run the
Speaker:simulations that I need to run. Well, that's not a trivial
Speaker:thing right now. It's like you're still
Speaker:programming in assembly language and that's not what most
Speaker:people want to do. So even that level, there's a
Speaker:lot of computer scientists and computer engineers that we need
Speaker:for those kind of activities to make sure that the industry is
Speaker:ready for those kind of use
Speaker:cases. Right. Right now. That's a good point.
Speaker:That's a good point. I think that it's always good when you hear someone else
Speaker:agree with you, what you're.
Speaker:But it looks like Candace had a question. No,
Speaker:I honestly, I was just gonna say I've enjoyed so much what we've talked about.
Speaker:Like there's so many follow ups that I'm gonna have that I'm gonna have
Speaker:to convince you to come back onto the show again, you know, in
Speaker:a little bit of time. I'll give you a break for a little bit but
Speaker:then come back because I just want to delve a little deeper into some of
Speaker:the, you know, you're really on the pulse of where
Speaker:this has to grow and you have a very unique
Speaker:perspective with all of your experience. You're
Speaker:fascinating. Thank you so much for all of this. I've loved it.
Speaker:That's what I was thinking. That's what I was thinking, Frank. Awesome.
Speaker:Awesome. Yeah. I want to be respectful of, of your time and.
Speaker:But this has been an enlightening conversation.
Speaker:It's interesting to think about how
Speaker:organizations have to start thinking in terms of quantum
Speaker:algorithms, even if they don't have a machine yet, even if they don't have
Speaker:access to the chips and whatnot,
Speaker:if anyone does. But I think it's important to start thinking about how
Speaker:to think differently today. Right. Because when this
Speaker:happens, and again, that timeline is anyone's guess,
Speaker:those who think ahead of the curve will
Speaker:be definitely in a more competitive advantage. So I actually had to write a
Speaker:trip report in regards to,
Speaker:you know, to me attending this Quantum conference. Right.
Speaker:And it was kind of like, well, you know, what's the impact to, you know,
Speaker:my day job as a Red Hat? Like, well, right now
Speaker:this is really an over. From the way I see it. Again, this is
Speaker:Frank speaking, not the company. This is an over the horizon
Speaker:technology from the point of view of a
Speaker:software company. So the best thing to do today is
Speaker:just kind of familiarize yourself with the concepts. So that way when it does come
Speaker:over the horizon, you're going to be in a much better position to
Speaker:adapt to the new situation on the ground. That's kind of my,
Speaker:you know, that was my elevator pitch.
Speaker:Now I would argue from the perspective
Speaker:that it's, I think it already is appearing
Speaker:on the horizon. So I think even those companies really should
Speaker:be careful not to fall behind. And those
Speaker:quantum technology companies that are out there have
Speaker:recognized that and now starting to develop their own kind
Speaker:of infrastructures. And like we had in the classical world
Speaker:computing world, we had, everybody had their own operating
Speaker:system, effectively. Of course, eventually
Speaker:most of it is now run on some version of Linux. Right,
Speaker:right. Red Hat supports.
Speaker:But I think there are a long ways away to getting in that
Speaker:direction when it comes to Quantum, for example. Yeah, that's fair, that's
Speaker:fair. But it's needed, I think,
Speaker:sooner than you think. I like that.
Speaker:Any parting thoughts, Candace? I like the sooner than
Speaker:you think. I do. I want to get that on a bumper sticker.
Speaker:Yeah, I do, I do. I think that there's a lot of, there's a lot
Speaker:of companies that are putting a lot behind this and, and many of them are
Speaker:still in stealth and, and you know, everyone's working towards, you
Speaker:know, who's going to break out with the first of, the first of something,
Speaker:you know, of which qubit or whatever or which, which technology it's going to, going
Speaker:to affect. But I think that just talking to people like
Speaker:Bert, you know, talking to other people that we've brought onto
Speaker:this podcast is really keeping everybody as informed as we
Speaker:possibly can be. And you know, I'm a big believer in the
Speaker:communication, so. Awesome. Yes.
Speaker:All right. And we'll let our. I'm sorry, go ahead. Any. Any parting thoughts
Speaker:where folks can find out more about you and your research?
Speaker:If people are interested in learning more about some of the research
Speaker:that I would say go take a look and just look up
Speaker:Quantum System Accelerator. You'll find all the
Speaker:information about all the awesome stuff that our center has
Speaker:done when it comes to advancing quantum computing and quantum
Speaker:sensing technologies, from the fundamentals to actually
Speaker:engineering systems. And generally
Speaker:LBL has some great information about
Speaker:all the research that they do because the Quantum System
Speaker:Accelerator is not the only one. We have also an advanced quantum testbed
Speaker:which by the way, industry can access if they really
Speaker:want to explore quantum and see if their
Speaker:applications could run on those kinds of systems. So there is
Speaker:a lot of different avenues, I think, for industry, for example, to
Speaker:engage with national labs. And of course, I'm representing
Speaker:the national labs here in this conversation and
Speaker:I think industry should really
Speaker:carefully look at the opportunities that could
Speaker:afford them. Excellent. And with that, we'll
Speaker:let our AI finish the show. And there you have it, Dear
Speaker:listeners, another episode of Impact Quantum wrapped up tighter
Speaker:than a qubit in a cryostat. Our thanks to the
Speaker:marvelous Bert De Jong for transporting us through the
Speaker:quantum multiverse without so much as a single wormhole
Speaker:mishap. If today's episode made you feel smarter,
Speaker:you're welcome. If it made you feel slightly bewildered,
Speaker:congratulations, you're paying attention. Be sure to
Speaker:check out the Quantum Systems Accelerator and Barclay
Speaker:Lab's other mind bending work, because as Bert rightly pointed out,
Speaker:the quantum future isn't five years away, it's practically
Speaker:parked outside. Remember to like, subscribe
Speaker:and share with that one friend who still thinks quantum is just a
Speaker:buzzword used by tech startups and sci fi
Speaker:screenwriters. Until next time, I'm Bailey, your
Speaker:semisentient host, signing off and reminding you
Speaker:when it comes to quantum, it's not about being certain,
Speaker:it's about being superposed.
