Japan Debuts First General-Purpose Quantum Computer Made of Light
spectrum.ieee.org
Most quantum computers need to be cooled to frigid temperatures or contained in space-like vacuum chambers. Using light to do the computation avoids both of those fates, but at a cost—how do you hold a light beam in your hand long enough to do the computation? There are many approaches, and now a team in Japan has created a light-based quantum machine that's capable of many different computations, and will be available on the cloud in 2025.

    Quantum computing. The nuclear fusion of computers. I wonder how long they will be 10 years away.

      Quantum computing is nothing like fusion, it’s been working for 20 years, just at smaller scales.

      A better comparison would be graphene. Graphene exists, we can make it, just not much of it. It won’t change everything until we can mass produce it.

      Fusion just plain doesn’t work (for generating energy) in practice yet.

    Honestly, this article makes some truly fantastic claims…

    It waves every “too good to be true” red flag I can imagine. But if it is true, it’s absolutely astounding. I mean look at the size of that package. And that for thousands of Qbits, no cooling required! So go ahead then, show us all this thing in action, go break some AES 512.

    Now we just need to find an example where quantum computing is actually faster, and not just because only one of the 2 were optimized.

      Can it simulate every possible playthrough of doom simultaneously?
