      @michael_nielsen I think #1 is the cardinal sin. Yes, it's true state space is exponential. But that's about internals, not functionality.

      @sigfpe @michael_nielsen AFAIK quantum computing doesn't offer exponential speedup. Is it true? If so, why?

      @vit_tucek @michael_nielsen It doesn't. I'm the annoying person who always corrects people who claim (or let it be understood) that it does.

      @sigfpe @vit_tucek No-one yet knows. It's not proven either way. Most QC people believe it probably does, but there are sensible skeptics

      @michael_nielsen @sigfpe Thanks! Is it proven at least in some axiomatic models of QC?

      @vit_tucek @sigfpe I don't know what an axiomatic model of QC is.

          @michael_nielsen @sigfpe I assumed that QC is axiomatized and in more than one way. I've heard that this is true in QFT.
