  1. Hello Mark: Has any consideration been given to increasing the “sparse interconnectivity” between qubits in your next generation of chips, since it has been one of the Google’s reasons for D-Wave not attaining the speed-up expected of it? Or even changing entirely the redesign of the next generation of chips which, as I understand it, will be a Herculean task! At any rate, wish you the best.

    • Hi Sol! Yes, every processor generation integrates as many productive changes as we can think of. Note that we reached parity with the very best the competition can do (more than a trillion $ of investment and ~ 60 years) with a tiny undercapitalized team in about 10 years, so saying we didn’t achieve the speed-up expected isn’t how I think of our monumental and unprecedented achievement.

      We’re in uncharted territory for this type of technology — all we can do is try to build the best computers that nature allows. We’re in the unfortunate position of having our real actual results compared against the most highly optimized industry on the planet (all silicon + all software) on the one hand, and a bunch of fantasy powerpoints (gate model computer) on the other hand. But we’ll beat them both, it’s just a matter of time.

    • University research is optimized for short, cheap projects. If you need time and capital they aren’t the right vehicle. It’s not that the people aren’t good, it’s just that they aren’t the right kinds of organizations to support this sort of work.

      • Hi Geordie: I completely agree with you. That’s why Dr. Laflamme’s IQC at U. of Waterloo, using dead-end NMR, won’t get out of the lab, despite spending millions of our tax money, since it’s partly financed by the Federal & Provincial government money.

  2. Hi Geordie,

    Regarding thermal noise:

    Perhaps technology should be designed that increases computational solvency while reducing data drag and degradation? A quantum computer, should be able to assess and anticipate the resources needed and adjust its own internal temperature to responsively “cancel out” its own thermal output (“radiant zero”).

    • Hi Walter, the systems are generally run at the lowest temperatures that can be achieved, as this usually (not always) increases performance. By their nature quantum computers are designed to be close to thermodynamically reversible. This can’t be achieved in practice but the closer you can get the better. Usually.
