Chinese Scientists Develop Photonic Quantum Analog Computing Chip (sciencemag.org) 55

hackingbear writes from a report via Xinhua: Chinese scientists demonstrated the first two-dimensional quantum walks of single photons in real spatial space, which may provide a powerful platform to boost analog quantum computing. Scientists at Shanghai Jiaotong University reported in a paper published in the journal Science Advances a three-dimensional photonic chip with a scale up to 49x49 nodes, by using a technique called femtosecond direct writing. Universal quantum computers, under develop by IBM, Google, Alibaba and other American and Chinese rivals, are far from being feasible before error correction and full connections between the increasing numbers of qubits could be realized. In contrast, analog quantum computers, or quantum simulators, can be built in a straightforward way to solve practical problems directly without error correction, and potentially be able to beat the computational power of classical computers in the near future.

    Develop? Bullshit. Which country did the Chinese scientists steal this technology from?

    • Yes, it was stolen-- in a collaborative effort involving, among other countries -- from, say, Austria [insidescience.org], as is the norm for scientific endeavors.

      Is China the Leader in Quantum Communications?

      Chinese scientists have built two major quantum infrastructure projects, and the race is on to take the next step.

    • Develop? Bullshit. Which country did the Chinese scientists steal this technology from?

      Just like all the otehr times, probably some country that didn't bother exploiting its intellectual property.

      If China can build it, more power to them.

    • You mean because they are Chinese and therefore not able to create? Let me guess... Only white people are able to create things?
      It's not the 80's you fucktard and you (the US) is not the best at everything.
      China has been dumping billions into quantom computing and green energy. Of course there are going to be advances.. you racist fuck.

  • that's what we'll name our band
  • Folks, it's just a matter of time before these Chinese beat us in fields that matter. They already are some of the best in the following fields: -

    Computer Science - Our computer innards speak to this

    Chemical Engineering - No wonder every home in the USA has something made in China

    Energy - They are "up there" when it comes to Solar Energy, Hydro Electricity & Wind turbines

    Chemistry - They start Chemistry as early as Middle School

    Decision Science - High/fast execution is their MO. talk of building a "sky

      Is Corning no longer the obvious best glass?

      That's news to me. Janky phones still seem to advertise it (albiet old).

    • Not sure what you are talking about. Our computer innards aren't from China and neither are our smartphones or batteries. You must be thinking of Korea or the US.
    • Computer Science - Our computer innards speak to this

      Process technology: Invented in USA
      Fastest microchips: Designed in USA or Israel (with USA-trained engineers.)

      Chemical Engineering - No wonder every home in the USA has something made in China

      The science is done in European and American universities (and by Corporations directly as well... like 3M or DuPont)

      Energy - They are "up there" when it comes to Solar Energy, Hydro Electricity & Wind turbines

      They are installing it quickly, but we're inventing it

      Decision Science - High/fast execution is their MO. talk of building a "sky scrapper" in 19 days!!

      O no! don't scrap the sky!

      Engineering - Results already speak for themselves: Talk of the largest High Speed rail Network in the world

      Who designed those trains again? Oh yeah, the Japanese.

      Materials Science - I bet your smartphone's screen or battery is made in China

      And designed in the USA or Europe, then made on contract in China.

    • Photon Torpedoes- If they reverse the polarity of neutrinos in the Photonic Quantum Analog Computing Chip, add some Higgs Bosons, and change Analog to Digital, the chip will produce Photon Torpedoes

      Does tinfoil protect against Photon Torpedoes, or do I need to invest in a new hat?

      • While I'm wating for the first Photon Torpedoes I already know I really need a Photonic Quantum Analog Computing Chip It'll be in a transparent casing in my laptop so everyone can see it.

    • High/fast execution is their MO. talk of building a "sky scrapper" in 19 days!!

      And perhaps falling down [gizmodo.com] even faster!!

    • This in no way should be taken to be a slam on China...
      But that list is not a list of fields that the Chinese have beat us, or are close to beating us in.

      Computer Science - Our computer innards speak to this

      The chance that you're typing this to me on a processor designed in China is very low, and if you are... Well, then you're using an inferior product, currently. The processor, as you know, is the part of a Computer where the Science in Computer Science is applied.

      Chemical Engineering - No wonder every home in the USA has something made in China

      This one makes me scratch my head... Every home in the USA having something made in China has

  • Why Photonic Quantum Analog? Because it *sounds* better!

    • I've been looking for a photonic quantum analog chip to put in my transspacial Heisenberg compensator... the femtosecond direct writing will really help improve the harmonic resonance manifold of my transwarp conduit.

        Don't forget to install a flux capacitor as well as putting it together with a hydrospanner and a sonic screwdriver. I hear the EPS relays are really hard to align precisely with the a flux capacitor without using a sonic screwdriver. More often than not you will also need to install a tribophysical waveform macro kinetic extrapolator and adjusting it with a cronometer. Remember that you will also need a borg transwarp coil in order to utilize the transwarp conduit. The chinese invented that chip just in

    • Why Photonic Quantum Analog? Because it *sounds* better!

      I guess we'll see Photonic Quantum Analog Tube Monster Cables real soon.

  • That is one buzzword-intensive abstract. On the other hand, I'd like to find a faux tonic quantum wok at Bed Bath and Beyond One Dimension.
    • It's for real, analoque quantum computing. It's not even that tough to see. I was out driving with polarized sunglasses after playing with IBMs quantum computer/tutorial, and realized there's a bunch of stuff you could do to help computer vision, just from working with light before digitizing using age old optics stuff derived from QM. You don't need the entire quantum computer to get a massive computational edge for certain things.

  • They are from somewhere else [atomchip.com]!

  • Just wait. We'll figure out if this is another Chinese "invention" powered by ass-blown smoke.
    Or, if it's real, just who they've stolen it from.

    Photonic because everything is better when done with lasers, right? Does you i7 make "pew pew" sounds?

    Quantum Not so bad, but add it to computing and the number of people who get it is drastically reduced

    Analog computing Because two states are never enough, we need 42
  • Why do "quantum computing" articles make me feel like they are talking about unobtainium, perpetual motion machines, or androids coming any-decade-now?

I've got a bad feeling about this.
