This is great news. But I heard that quantum computers are so fast that they can easily crack the security code. Is it true ? How can we make our future communication secure if quantum computers are commercialized.
Writing software for such as beast would be almost impossible. In fact it would be counter productive to have the software ride on the Qunatum computers -- it will drag their effective speed down to halt!
Supercooling experimental devices is often done just to simplify the experiements, with the final production units optimized for running at room temperature. However, in this case the superconducting JJs are dependent on the supercooling, so they may end up like mag-lev trains--requiring cyrogenics even in normal use.
Hey, I'm old enough to be used to that (6502, Z-80, PDP-11, M68K, etc.) unlike programmers today who only have to contend with the latest x86 incarnations. It's amazing how software has actually been able to make progress when CPU architectures don't get radical makeovers every six months or so.
One thing I have not heard is whether or not anyone is working on the software for this beast. Speaking as someone who has written a few lines of code, I have no idea how to program for it. I am pretty sure that the OS is going to be more involved than just doing a Linux port, and I suspect that applications are also going to have to be written differently. Is anyone working on this, or are you hardware guys just going to pitch it over the fence when you are done? :-)
I read it as they had to super cool the apparatus to slow it down enough to measure it with today's equipment. This leads one to question whether or not they can maintain the millisecond coherence time 'at speed' - when the apparatus is not super cooled?
