Transcript
- 0:01Speaker 1: Welcome to the quark Side Quantum Physics Podcast, an exploration
- 0:05Speaker 1: of the fundamental structure of reality where quantum laws govern matter, energy,
- 0:11Speaker 1: and information. Here, uncertainty is a feature, not a flaw,
- 0:16Speaker 1: and understanding begins at the smallest scales.
- 0:27Speaker 2: I want you to imagine, just for a second, a
- 0:29Speaker 2: world where teleportation isn't you know, some parlor trick or
- 0:33Speaker 2: a sci fi movie.
- 0:34Speaker 3: Trope, right, like something out of Star Trek.
- 0:36Speaker 2: Exactly. Imagine a reality where ultrafast quantum computing and like
- 0:42Speaker 2: instant fundamentally unhackable information transfer are just the everyday backbone
- 0:49Speaker 2: of our technology.
- 0:50Speaker 3: It's wild to think about it, really is.
- 0:52Speaker 2: You wake up, you log on, and you use a
- 0:54Speaker 2: global network that shares data with zero lag and perfect security,
- 0:59Speaker 2: and all of it relies on the strangest, most mind
- 1:02Speaker 2: bending rules of the universe.
- 1:04Speaker 3: Yeah, the rules that defy all classical logic.
- 1:07Speaker 2: Welcome back to the Deep Dive. If you're new here.
- 1:10Speaker 2: This is the show where we take a massive stack
- 1:12Speaker 2: of recent research articles, technical papers and we extract the
- 1:16Speaker 2: absolute most important insights you need to know.
- 1:18Speaker 3: And today is a big one.
- 1:20Speaker 2: It is huge. Today our mission is to break down
- 1:22Speaker 2: a freshly unveiled twenty twenty six scientific breakthrough from researchers
- 1:26Speaker 2: at Kyoto University and Hiroshima University in Japan.
- 1:29Speaker 3: Yeah, they've done something incredible.
- 1:31Speaker 2: They have finally cracked a twenty five year old quantum puzzle,
- 1:36Speaker 2: and in doing so, they've basically brought next generation quantum
- 1:39Speaker 2: networks right to our doorstep.
- 1:41Speaker 3: Okay, let's unpack this because to really grasp how we
- 1:45Speaker 3: are making this leap from a theoretical dream into hard,
- 1:50Speaker 3: functual infrastructure, we need to talk about the raw material
- 1:54Speaker 3: making it all possible.
- 1:55Speaker 2: Yeah, it really is a profound paradigm shift, because before
- 1:58Speaker 2: we can dive into how the these Japanese researchers crack
- 2:01Speaker 2: the code to actually read these complex quantum systems, we
- 2:04Speaker 2: have to look at how our relationship with quantum entanglement
- 2:07Speaker 2: has completely evolved. Right now, we know you listeners follow
- 2:10Speaker 2: this space, so we aren't gonna bore you with the
- 2:11Speaker 2: whole Shrewdinger's cat thing or basic particle physics one oh one.
- 2:15Speaker 2: You already know what entanglement is, right, the.
- 2:17Speaker 3: Idea that subatomic particles like photons can become so deeply
- 2:22Speaker 3: linked that their properties just can't be understood individually anymore, exactly.
- 2:26Speaker 3: Try have to treat the whole system as a unified
- 2:28Speaker 3: reality exactly. But what's vital to understand here is the
- 2:33Speaker 3: philosophical shift. In the scientific community. For decades, entanglement was
- 2:38Speaker 3: viewed mostly as a headache.
- 2:40Speaker 2: We're really complicated headache.
- 2:42Speaker 3: Yeah. It famously troubled Albert Einstein. He called it spooky
- 2:45Speaker 3: action at a distance because it seemed to completely violate
- 2:48Speaker 3: the classical rules of reality.
- 2:50Speaker 2: Right, it broke all's rules.
- 2:51Speaker 3: It was a curiosity, a puzzle to be observed. But
- 2:54Speaker 3: today it is the actual tangible raw material for a
- 3:01Speaker 3: new industrial revolution. It is like the clay we're trying
- 3:06Speaker 3: to mold.
- 3:06Speaker 2: Which is still incredibly spooky when you think about it.
- 3:09Speaker 2: I mean, even if we accept it as raw material,
- 3:11Speaker 2: it defies everyday logic.
- 3:13Speaker 3: Oh absolutely.
- 3:13Speaker 2: Imagine you have a pair of magic dice. If you
- 3:16Speaker 2: roll one of those dice in New York and it
- 3:17Speaker 2: lands on a six, the entangled die sitting in a
- 3:20Speaker 2: server room in Tokyo instantly rolls a six, no matter
- 3:23Speaker 2: the distance between them, instantaneously, right, no wires, no physical signals,
- 3:28Speaker 2: just an instant link. But wait, if it's just spooky action,
- 3:31Speaker 2: How do we actually use it to build a computer?
- 3:33Speaker 2: How do you take that magic trick and turn it
- 3:35Speaker 2: into a reliable machine.
- 3:36Speaker 3: This raises an important question because it gets to the
- 3:39Speaker 3: very heart of the engineering bottleneck. Okay, in a classical computer,
- 3:43Speaker 3: your infrastructure is built on transistors reading physical states as
- 3:47Speaker 3: simple ones or.
- 3:48Speaker 2: Zeros, right, standard binary exactly.
- 3:51Speaker 3: But in a quantum computer, you are using the entangled
- 3:54Speaker 3: state itself to perform calculations and route information.
- 3:58Speaker 2: Wow.
- 3:59Speaker 3: Okay, yeah. By treating a system of entangled particles as
- 4:02Speaker 3: a unified whole, any manipulation of the system inherently processes
- 4:06Speaker 3: vast amounts of data simultaneously.
- 4:09Speaker 2: So it's exponentially faster.
- 4:10Speaker 3: Right. So creating the entanglement is step one. But the
- 4:14Speaker 3: real challenge, the thing that has held up the quantum
- 4:17Speaker 3: Internet for decades, is step two, which is what figuring
- 4:20Speaker 3: out how to measure or read that entanglement without destroying
- 4:24Speaker 3: its usefulness.
- 4:25Speaker 2: Ah. I see. So if entanglement is our magic clay,
- 4:29Speaker 2: it's not enough to just mash the clay together. If
- 4:32Speaker 2: you actually want to process information, you have to be
- 4:34Speaker 2: able to look at the clay and know exactly what
- 4:36Speaker 2: shape it to.
- 4:36Speaker 3: Me precisely creating entangled states in a laboratory is something
- 4:40Speaker 3: physicists have actually gotten quite good at. Oh really, Yeah,
- 4:43Speaker 3: but just throwing photons together isn't enough. You have to
- 4:46Speaker 3: reliably verify what kind of entangled state you have created,
- 4:51Speaker 3: purely and accurately, right.
- 4:52Speaker 2: You need to know what you made exactly.
- 4:54Speaker 3: And for years, the standard method for doing this was
- 4:57Speaker 3: something called quantum tomography.
- 4:59Speaker 2: Tomography like a CT scam in a hospital.
- 5:03Speaker 3: Similar concept, yeah, but infinitely more frustrating. At the quantum level.
- 5:07Speaker 3: Quantum tomography tries to estimate a quantum state by taking
- 5:11Speaker 3: thousands upon thousands of measurements of identical copies of that state.
- 5:14Speaker 2: That sounds exhausting, it is.
- 5:16Speaker 3: It's basically a statistical guessing game, and it has a
- 5:19Speaker 3: fatal mathematical flaw. As you add more photons to the system,
- 5:23Speaker 3: the number of measurements you need to take grows explosively.
- 5:27Speaker 3: It scales exponentially.
- 5:29Speaker 2: Wow. So, if I'm trying to build a fast network,
- 5:31Speaker 2: quantum demography is basically like trying to figure out a
- 5:33Speaker 2: wedding kick's exact recipe by tasting it one microscopic crumb
- 5:37Speaker 2: at a time. Yeah, Like, Okay, this crumbhusbandilla, let me
- 5:40Speaker 2: test the next crumb. It takes forever, and by the
- 5:42Speaker 2: time you've mapped the whole cake, the data is useless.
- 5:44Speaker 2: You've completely bogged down the network.
- 5:46Speaker 3: That is a perfect way to visualize it. You are
- 5:49Speaker 3: destroying the system crumb by crumb to guess the recipe.
- 5:52Speaker 2: So what's the alternative.
- 5:54Speaker 3: The solution to this massive bottleneck is something called an
- 5:57Speaker 3: entangled measurement.
- 5:58Speaker 2: Okay.
- 5:59Speaker 3: Instead of looking at into visual crumbs, an entangled measurement
- 6:02Speaker 3: allows scientists to identify a specific complex entangled state in
- 6:07Speaker 3: a single shot. You measure the whole cake at once.
- 6:11Speaker 2: Which sounds way more efficient.
- 6:12Speaker 3: It is, and scientists had already proven this single shot
- 6:16Speaker 3: method was possible for one specific type of entanglement known
- 6:20Speaker 3: as the GHz state GC. Yeah, named after the physicists Greenberger,
- 6:25Speaker 3: Horn and Xylander.
- 6:26Speaker 2: Okay, got it.
- 6:27Speaker 3: But there is another vastly more important type of multiphoton
- 6:31Speaker 3: entanglement called the W state, And for twenty five years,
- 6:35Speaker 3: a single shot measurement for the W state remained entirely
- 6:38Speaker 3: out of reach, completely impossible.
- 6:40Speaker 2: Okay, I have to ask why was this WO state
- 6:43Speaker 2: so uniquely difficult? What makes it different from the GHz state.
- 6:47Speaker 3: What's fascinating here is the mechanics of how the entanglement
- 6:50Speaker 3: is distributed. Think of the GHD state like a very
- 6:52Speaker 3: rigid house of cars. If you measure one photon, it
- 6:56Speaker 3: immediately determines the state of the others in a very strict,
- 7:00Speaker 3: predictable way. But because it's so rigid, it's also incredibly fragile.
- 7:05Speaker 2: Like blowing on a house of cards.
- 7:07Speaker 3: Exactly, if you lose a single photon to environmental noise,
- 7:11Speaker 3: the entire entangled system collapses. The W state, though, is
- 7:15Speaker 3: entirely different. It is characterized by a shared distributed.
- 7:19Speaker 2: Entanglement distributed how the.
- 7:21Speaker 3: Quantum information is smeared delicately across all the photons.
- 7:25Speaker 2: Oh wow, so it's less like a house of cards
- 7:27Speaker 2: and more like, uh, a safety net.
- 7:29Speaker 3: Exactly, if you lose a photon in a W state,
- 7:33Speaker 3: the remaining photons actually stay entangled.
- 7:35Speaker 2: That's amazing.
- 7:36Speaker 3: It is incredibly robust against noise and particle loss, which
- 7:39Speaker 3: is exactly why it is the holy grail for real
- 7:41Speaker 3: world quantum networks.
- 7:43Speaker 2: Right because the real world is messy, Right, You.
- 7:45Speaker 3: Want that durability. If you're sending data under city streets.
- 7:49Speaker 3: But that very same distributed smeared nature made it agonizingly
- 7:53Speaker 3: difficult to mathematically design a measurement that could identify it
- 7:56Speaker 3: in a single shot.
- 7:57Speaker 2: Here's where it gets really interesting, because Shigeki ta Kuchi
- 8:00Speaker 2: and the university teams in Japan didn't just try to
- 8:04Speaker 2: smash these W states with brute force.
- 8:07Speaker 3: No they didn't.
- 8:08Speaker 2: According to the research, they found a structural workaround. They
- 8:12Speaker 2: successfully performed a single shot entangled measurement identifying the W
- 8:17Speaker 2: state using three photons.
- 8:19Speaker 3: Yeah, a massively.
- 8:20Speaker 2: And they did it by looking for something called cyclic
- 8:22Speaker 2: shift symmetry. Let me try to wrap my head around
- 8:25Speaker 2: that is cyclic shifts symmetry kind of like a musical chord.
- 8:30Speaker 3: A musical chord.
- 8:31Speaker 2: Yeah, Like think of a C major chord on a
- 8:33Speaker 2: piano c eng If you move the seed to the
- 8:36Speaker 2: top so it's EGC, it's still fundamentally a C major chord.
- 8:40Speaker 2: It's an inversion.
- 8:41Speaker 3: Oh, I see where you're going, right.
- 8:42Speaker 2: No matter how you cycle or shift those specific notes around,
- 8:46Speaker 2: the underlying harmony stays perfectly recognizable.
- 8:48Speaker 3: That is a brilliant analogy. Yes, even as the specific
- 8:52Speaker 3: configurations of the photons shift within the system. There is
- 8:55Speaker 3: a fundamental symmetrical property, a underlying harmon that defines the
- 9:01Speaker 3: entire system as a W state.
- 9:03Speaker 2: Okay, so how do they actually measure that?
- 9:05Speaker 3: To actually detect this cord, the Japanese researchers designed a
- 9:08Speaker 3: highly specialized photonic quantum circuit.
- 9:11Speaker 2: Built out of light.
- 9:11Speaker 3: Built out of light, This circuit performs something called a
- 9:14Speaker 3: quantum fourya transformation, specifically tailored for W states.
- 9:19Speaker 2: A four EA transform. I know that's used in audio
- 9:22Speaker 2: engineering to break down complex sound waves into individual frequencies.
- 9:26Speaker 2: How does a quantum circuit do that to light?
- 9:28Speaker 3: Well, In a traditional computer, a Fouria transform is a
- 9:31Speaker 3: really heavy mathematical calculation. But in this photonic circuit, the
- 9:36Speaker 3: math is done physically by the light itself.
- 9:39Speaker 2: Wait, physically yeah.
- 9:41Speaker 3: The circuit uses an intricate web of beam splitters and
- 9:43Speaker 3: phase shifters. As the entangled photons travel through these paths,
- 9:47Speaker 3: their light waves naturally interfere with each other.
- 9:50Speaker 2: Oh wow.
- 9:51Speaker 3: This physical interference acts as the calculation, taking that hidden
- 9:55Speaker 3: shifting symmetry of the W state and naturally amplifying it
- 9:59Speaker 3: into a clear, measurable signal at the output.
- 10:01Speaker 2: That is wild.
- 10:02Speaker 3: They literally built an optical machine that naturally filters for
- 10:05Speaker 3: that specific quantum harmony.
- 10:07Speaker 2: That is incredible. But you know, the paper also notes
- 10:09Speaker 2: that they fed three single photons into this device, and
- 10:13Speaker 2: they were looking at the fidelity of the results, right,
- 10:16Speaker 2: fidelity fidelity being the probability that the device gives the
- 10:20Speaker 2: right result when it's fed a pure W state. Does
- 10:23Speaker 2: this mean the machine still makes mistakes? I mean, if
- 10:26Speaker 2: we are building an ultra secure Internet of the future,
- 10:29Speaker 2: we can't have a router that just drops packets or
- 10:32Speaker 2: misreads data because of probability error.
- 10:35Speaker 3: Right, it's very valid concern, But in quantum mechanics, fidelity
- 10:39Speaker 3: doesn't mean the machine is glitching or making a software error.
- 10:42Speaker 2: Okay, so what does it mean.
- 10:44Speaker 3: It's a measure of absolute precision against microscopic environmental noise.
- 10:49Speaker 3: No physical system is ever one hundred percent perfect, but
- 10:52Speaker 3: achieving a highly elevated fidelity means the fundamental mechanism is
- 10:56Speaker 3: definitively proven.
- 10:58Speaker 2: So it works.
- 10:58Speaker 3: It works, But honestly, the fidelity isn't even the most
- 11:01Speaker 3: groundbreaking part of the device. The real game changer is
- 11:04Speaker 3: its stability. This entire optical circuit is passive.
- 11:08Speaker 2: Wait passive that defies everything I know about quantum labs.
- 11:11Speaker 2: Usually you see these giant gold, steampunk chandeliers hanging inside
- 11:16Speaker 2: deep freeze vacuum chambers.
- 11:18Speaker 3: Oh yeah, the dilution refrigerators, right, and.
- 11:20Speaker 2: They require a whole team of postdocs constantly tweaking lasers
- 11:24Speaker 2: just to keep the experiment alive for like a millisecond exactly.
- 11:28Speaker 3: Traditional quantum setups are agonizingly fragile, but this team built
- 11:33Speaker 3: a device out of light that ran for an extended
- 11:36Speaker 3: period without any active real time control or continuous calibration.
- 11:40Speaker 2: It just ran on its own.
- 11:42Speaker 3: They remain highly stable on its own. Yeah, And proving
- 11:44Speaker 3: that we can achieve high fidelity readings on a stable
- 11:47Speaker 3: passive device is the turning point. It proves we don't
- 11:51Speaker 3: need a perfectly pristine, constantly adjusted, million dollar laboratory to read.
- 11:56Speaker 2: These networks, which means we can actually take the technology outside.
- 11:59Speaker 2: We can out of the lab and start bolting it
- 12:01Speaker 2: into actual city infrastructure.
- 12:03Speaker 3: Exactly, we can put it in the real world.
- 12:05Speaker 2: And that transition into the real world brings us to
- 12:08Speaker 2: the actual teleportation networks. Just to be absolutely clear for
- 12:12Speaker 2: everyone listening, we are talking about beaming data instantaneously, not
- 12:17Speaker 2: beaming humans like on Star Trek, right, right.
- 12:19Speaker 3: It is vital to be precise with the terminology. Quantum
- 12:23Speaker 3: teleportation is the transfer of quantum information from one location
- 12:27Speaker 3: to another without physically moving any matter through the space
- 12:30Speaker 3: between them.
- 12:31Speaker 2: So we aren't mailing a photon.
- 12:33Speaker 3: No, you aren't sending a photon in a microscopic FedEx
- 12:36Speaker 3: box from point A to point B. You are utilizing
- 12:39Speaker 3: that entangled link we talked about at the beginning to
- 12:42Speaker 3: instantly transfer the exact quantum state of a particle in
- 12:45Speaker 3: location A onto a completely different waiting particle in location B.
- 12:49Speaker 2: And what blows my mind is the timeline of how
- 12:51Speaker 2: fast this is moving. The source of show that in
- 12:53Speaker 2: late twenty twenty five researchers achieved all photonic quantum teleportation
- 12:58Speaker 2: in a hybrid urban network. Yes, a major milestone, and
- 13:01Speaker 2: they did it using something called quantum dots. What exactly
- 13:03Speaker 2: is a quantum dot doing in a city network?
- 13:05Speaker 3: A quantum dot is essentially a tiny nanoscale semiconductor crystal.
- 13:10Speaker 3: You can think of them as artificial atoms. Artificial atoms, yeah,
- 13:13Speaker 3: because of their size, they trap electrons in a way
- 13:15Speaker 3: that allows them to emit single photons on demand. Very predictably.
- 13:20Speaker 2: Oh, I see, in a.
- 13:21Speaker 3: Hybrid urban network, you need a reliable, high quality source
- 13:25Speaker 3: of single photons to carry the quantum information, and quantum
- 13:28Speaker 3: dots act as those perfect little photon factories interfacing between
- 13:32Speaker 3: different types of quantum hardware across the city.
- 13:35Speaker 2: So they are generating the data carriers. And the pace
- 13:38Speaker 2: of this is just staggering, because right after that urban
- 13:41Speaker 2: network test in twenty twenty five, twenty twenty six saw
- 13:44Speaker 2: another massive leap.
- 13:46Speaker 3: It really did.
- 13:47Speaker 2: The reports show a completely different team built an integrated
- 13:50Speaker 2: photonic chip capable of manipulating and measuring complex multipart entanglement
- 13:55Speaker 2: all on a single tiny device.
- 13:57Speaker 3: Incredible miniaturization right.
- 13:59Speaker 2: And perhaps most impressively, also in twenty twenty six, researchers
- 14:03Speaker 2: tested a three node quantum network right across existing standard
- 14:07Speaker 2: fiber optic cables in New York.
- 14:09Speaker 3: City using standard cables.
- 14:10Speaker 2: Yeah, they did this using a process called entanglement swapping.
- 14:13Speaker 2: How exactly do you swap entanglement under the streets of Manhattan.
- 14:17Speaker 3: Entanglement swapping is essentially a quantum relay race. Imagine you
- 14:22Speaker 3: have three nodes in the network, Alice, Bob and Charlie Okay,
- 14:25Speaker 3: Alice and Bob are far apart and have never interacted,
- 14:29Speaker 3: but they both share an entangled link with Charlie, who
- 14:31Speaker 3: is sitting in the middle.
- 14:32Speaker 2: So Charlie is the hub.
- 14:33Speaker 3: Right, Charlie performs a specific entangled measurement on his particles.
- 14:38Speaker 3: Because of the rules of quantum mechanics, the very act
- 14:41Speaker 3: of Charlie taking that measurement instantly causes Alice and Bob's
- 14:45Speaker 3: particles to become entangled with each other, even though they've
- 14:47Speaker 3: never met.
- 14:48Speaker 2: Wait, really that fast.
- 14:50Speaker 3: Instantly, Charlie just swapped the entanglement to them. This is
- 14:53Speaker 3: how you route a quantum connection over long distances, bouncing
- 14:56Speaker 3: it from node to node through the messy temper fluctuating
- 15:00Speaker 3: fiber cables under New York.
- 15:02Speaker 2: And if we connect the dots here, the Japanese team's
- 15:05Speaker 2: W state breakthrough is the ultimate missing piece for that
- 15:09Speaker 2: relay race. You can have the fiber cables, you can
- 15:12Speaker 2: use entanglement swapping to rout the signal, and you can
- 15:15Speaker 2: use quantum dots to generate the photons. But to make
- 15:18Speaker 2: it work at scale without lagging, you need to be
- 15:21Speaker 2: able to verify that the robust W state information actually
- 15:26Speaker 2: arrived correctly yes, you need an ultrafast single shot scanner.
- 15:31Speaker 2: Without this new Kyoto and Hiroshima circuit, the New York
- 15:34Speaker 2: network would just get bogged down trying to read the
- 15:36Speaker 2: cake crumb by chrome.
- 15:38Speaker 3: If we connect this to the bigger picture, yes, they
- 15:41Speaker 3: have provided the high speed optical scanner for the future Internet,
- 15:44Speaker 3: and they were already planning their next moves.
- 15:46Speaker 2: Oh, what's next.
- 15:47Speaker 3: The researchers intend to extend this passive method to larger
- 15:51Speaker 3: multiphoton states, well beyond just three photons, and they're actively
- 15:56Speaker 3: working to develop on ship photonic circuits to make it
- 15:59Speaker 3: even small. They want to make the process of reading
- 16:01Speaker 3: these states faster, smaller, and vastly more practical for mass production.
- 16:06Speaker 3: They are literally laying the bricks for a fundamentally unhackable Internet.
- 16:10Speaker 2: Completely unhackable because.
- 16:12Speaker 3: In a quantum network, information cannot be intercepted or copied
- 16:16Speaker 3: by a hacker without instantly destroying the state and alerting
- 16:19Speaker 3: the sender. It represents the absolute pinnacle of data security.
- 16:24Speaker 2: So what does this all mean. Let's pull all these
- 16:26Speaker 2: threads together. We started with the basic reality of quantum entanglement,
- 16:30Speaker 2: a concept so bizarre that it made Einstein's headspin.
- 16:34Speaker 3: It definitely did.
- 16:35Speaker 2: For decades. Even as we learned to create that spooky
- 16:38Speaker 2: action in pristine labs, we were stuck at a massive
- 16:41Speaker 2: engineering bottleneck. We could make the magic clay, but we
- 16:44Speaker 2: couldn't read it efficiently because quantum tomography was just too
- 16:47Speaker 2: slow and destructive, way too slow. Then this massive twenty
- 16:50Speaker 2: twenty six breakthrough happens. Researchers in Japan finally figure out
- 16:54Speaker 2: how to instantly read the highly complex durable W state.
- 16:57Speaker 3: In a single shot, such a huge deal.
- 17:00Speaker 2: They use cyclic shift symmetry to physically listen for the
- 17:03Speaker 2: underlying musical cord of the photons using a completely passive
- 17:08Speaker 2: light based circuit. And this is all happening concurrently with
- 17:11Speaker 2: massive real world strides miniaturized quantum chips, single photon quantum dots,
- 17:16Speaker 2: and actual teleportation networks swapping entanglement through the dirty fiber
- 17:21Speaker 2: optic cables under New York City.
- 17:23Speaker 3: It's all coming together at once, it really is.
- 17:25Speaker 2: I really want you the listener, to think about how
- 17:28Speaker 2: this transforms the reality you interact with every day. We
- 17:32Speaker 2: are moving away from fragile science experiments and toward actual
- 17:35Speaker 2: durable chips that will power the communication networks you will
- 17:39Speaker 2: use in the near future. The quantum Internet isn't one
- 17:42Speaker 2: hundred years away, It's actively being built right beneath our feet.
- 17:45Speaker 3: It truly is the dawn of a new era of infrastructure,
- 17:49Speaker 3: and as we transition from struggling to read just three
- 17:51Speaker 3: entangled photons to eventually networking billions of them across global
- 17:55Speaker 3: fiber optics, it forces us to ask a profound question,
- 18:00Speaker 3: what happens to our traditional concepts of distance, time, and security.
