Photonic qubits cannot be programmed. Each algorithm needs its own dedicated hardware circuit. Also any manufacturing defects can massively impact the quality and validity of the computation results. The only good thing I can say about photonic qubits are they have much better coherence than transmon or charge qubits. If you're the NSA and have the resources to pour into solving one very specific task, like breaking 256-bit encryption) it may be the way to go but for everyone else they will be pursuing this technology using superconducting qubits.

[@puffthemagiclepton7534]

@@jakubiskra523 Sorry, you are right on that part. Manufacturing defects can affect the viability of any chip. Where quantum processing and classical differ here are that you can control which circuits get executed on a classical chip via gates. Those operations can be sequenced depending on other gates to perform some useful operation. Since we are limited in the number of qubits that can be produced its an issue for quantum computers. With superconducting qubits you can create any circuit you want from a limited number of qubits because the quantum gates are microwave pulses that get applied to each qubit. You can code the whole algorithm as a sequence of microwave pulses that get applied and at the end measure the state of the qubits. For example, you could perform a Hadamard transformation with one pulse on a pair of qubits, execute a CNOT operation on a pair, and then another Hadamard transformation on the first qubit with three microwave pulses. With a photonic quantum computer I would need to physically construct the optical paths through a phase shifter, a nonlinear crystal, and another phase shifter. Then if I wanted do something else I would need to physically construct the optical paths to do those operations.

[@sasanitos]

Nice hyped news. I saw that article as well. However, the motivation that was presented in your clip was a bit missleading. It is true that superconductive based qubits need cooling, but so does photonic based quantum computing. To make sense of any of the operations that made by photons, one has to measure, and the measurement is done by single-photon detectors. Commonly, the most efficient detectors are superconductive nanowire single-photon detectors that also require cryogenic cooling. So back to using the FRIDGE again. Also, one major hurdle about the photonic quantum computing is loss that is inherent to the photons propagating in the waveguides as well as the fabrication imperfections the waveguides. Until we find an extremely low loss material, improve the fabrication processes to achieve atomically smooth surfaces, and coming up with a single photon source with a high emission rate, photonic quantum computing will remain a nice lab demonstrator. I think trapped ions have a better chance of becoming the fully programmable universal quantum computer than other approaches.

Photons can have an infinite number of polarizations. Vertical and horizontal polarizations are merely two that are very easy to distinguish from each other, making it suitable for binary computing.

[@chirpedpulse5528]

Your comment is somehow misleading. Horizontal (H) and vertical (V) are one (of infinite possible) bases. But all other bases can be formed as superposition of H and V, so you can only choose two for encoding information and thus only generate qubits (2D). However, there are many other encodings such as orbital-angular momentum, path, time, energy. In fact, the paper presented here uses energy (=frequency) and is therefore able to generate qudits (D>2).

[@edwarddejong8025]

Photons are wonderfully fast but are terrible to control. Because they have no electrostatic charge (like a neutron) you can't steer them, except inside a fiber optic cable. Electrons on the other hand you can conduct in a wire, and start and stop them pretty quickly (nano seconds). This is why all of our chips are based on the maneuverability and controllability of electrons. We use photonics very commonly now in data centers for high speed links between computers, as fiber optics can transmit at high speed over long distances due to the purity of the glass fibers, using the principle of total internal reflection. But we currently only use optical systems for transport, and once it hits the network interface modules on your switch it gets converted to ethernet packets in digital form (a serial signal). 1, 2.5, 5, 25, 50, 100 gigabits per second are the speeds currently sold in switches. Most home equipment is 1 Gigabit, which is enough for almost any family. That photonic chip is a cute, very small scale proof of concept type of device, but 3000 entangled pairs per second is a pathetic speed, and given we are pushing around a million times that rate via electrons currently, means that it will be many decades before photonic systems are in use for anything but dumb transfer. But it is a fascinating research area, and should be supported, as we are nearing the limits of what can be accomplished with electrons.

I just realized that we don’t need nano scale LED’s and image sensors to make a photonic computer. We can just have nano-scale (or micro-scale) ‘doors’ to open and close to let light in and out at the right places at the right time. Now of course we would need to figure out how to get a very tiny sized fire optic cable into our computer, because simply coating a substrate in a film of silver won’t cut it. Maybe the wafer itself will be made of a pure silica wafer, that would be cut into micro or nano scaled slices. These slices will have circuitry printed onto them and have solid reflective materials coated on the printed circuits. Then the appropriate layers would be stacked precisely on top of one another.

The biggest problem that photonic quantum computers have is the ability to trap qubits. Some operations like quantum cryptography would require you to be able to store qubits for extended periods of time or else a lot of its security guarantees go away (for example BB84 is trivially broken). It is not exactly easy to trap light in one place, especially in a way where you don't interact with it to change its state. Although, there are other uses that don't require this, such as, Shor's algorithm, so they could still be useful.

You can choose the basis as by your perference. Anyhow, the photons were encoded in frequency here. There are many protocols, but you are right in that way that the computational power increases exponentially this the number N in one state.

[@baconsalad1891]

By creating a artificial tunnel around the photon forces it to operate in a measured state . Meaning , even if it was not being viewed the photon would not be able to move like a wave as it’s being isolated within the boundaries of the tunnel. This simulates the same Gravity tunnel that is being produced when you are viewing or measuring a photon. It is my belief that if the laser pulsates at tremendously fast speeds it may cause the triggering of gravity to create its tunnel causing a over lap in Gravity. This theoretically means the photon may be in a slightly dilated state of Time. This might allow for more clusters to be bunched together. You can have an offset of clustered entangled photons that can off calculate.

Very interesting. This could be an important step towards making quantum computing usable. I've always found the term 'entangled' to be misleading. It makes it sound like the two photons are connected in some way but it seems to me they are just synchronized. It's like setting two perfect watches to the exact same time. No matter how far you separate them, they both tell the same time. But if you change the time on one of them, it doesn't change the time on the other, so it can't be used to send messages faster than the speed of light. At least that's how I see it.

@@Bal3472-e4b I think the key is for both observers to make the measurement at the same time, but that would mean communication wouldn't be bidirectional instead it would be like a walkie-talkie. As for the latency, establishing the connection cannot be done faster than the speed of light, but once the connection has been established you could send information to a location in a different solar system instantly despite light taking years to travel such a distance

How long do photons remain entangled? What percentage of photons are entangled? Can previously entangled photons be entangled with more photons, creating clusters or chains? Does it overwrite the previous entanglement or extend it further?

[@AndrewMann205]

If you split a photon do you have two entangled half photons? Are all photons equal in energy density and dimension?

Even in terms of classical computing, the photonic computer is mind-blowing, so to combine it with quantum capabilities is incredible. To be honest, I don't expect this kind of quantum computer for tomorrow but this breakthrough will lead us to photonic classical computing and that's really great ! Thanks for this good news and for letting us know about it !

After 20 years first quantum computer arrives. 50 years from now people will be watching 240hz 8k gigantic micro led tvs and your phone camera will be as good as a professional. Phones will have the power of a ps4 pro and loading times will be non existent. Fast forward a 100 years and we get singularity ai.

I'm just wondering what happens when AGI starts running on a photonic quantum computer. I don't understand why it was so difficult to shrink a laser though isn't it pretty much light from a light emitting diode being made coherent? Could you talk a little about what the challenge was there?

[@chirpedpulse5528]

Hi Amoroso, the technical challenge was to get the light emitting part (an indium phosphide gain section) on the silicon nitride chip, as the light must stay inside the waveguide. Second, "being made coherent" is not as trivial as it sounds on a photonic chip, especially as we want to have a small linewidth. The Vernier effect was used here to achive this. Further, you have to think about many technical details such as how strong should the coupling into the rings be such that laser action can happen and so on.

[@amorosogombe9650]

@@chirpedpulse5528 Got it. Thank you. I figured that a photon is so small that 1mm may as well be a km to it so as long as you could create a sufficiently small gain medium etched into the substrate e.g. by chemical vapour deposition or whatever then you should be able to get a laser in there but it's clearly more complicated than that. One thing is still bugging me though. If all photons are already entangled by virtue of coming out of the big bang singularity, then what new entanglement is happening now?

[@MozartificeR]

Its a Major breakthrough, cos 8000 entangled pairs, solves the problem of integration. I do have one question though. How much decoherance is there? Do we have a Volvo or a Ferarri?

[@dustysoodak]

Anyone know what this particular "entanglement" operation does? As in what does the state |0> go to and what does the state |1> go to? So far, every example of a purely optical quantum computer I've seen requires filtering of bad results from logic gates that is proportional to the number of possible states (2^num_of_qbits), so isn't useful for general purpose computing unless someone comes up with a clever way to translate into regular qbit operations that is scalable (there is a company in BC Canada that is evidently working on this).
