Has quantum computing ever been:

(a)    indisputably demonstrated;
(b)    shown to be scalable, even in principle and assuming "errors" can be adequately controlled;
(c)    and can any Linker please explain how QC hardware is thought to work, in principle?  I've seen some pretty bizarre explanations over the years.

Regarding (c), I suspect some QC hardware is architected around neural network processors, but it would be interesting to know why quantum physics at very low temperatures is necessary.

The great English physicist  & cosmologist Roger Penrose gave an after-dinner speech at an American University some years ago in which he speculated that creative (i.e. non-deductive) thought may only be possible because the human brain includes some quantum processing, even at room temperature.  I _should_ still have the audio file and a separate presentation (Powerpoint?) which shows his whiteboard diagrams if  any Linker would like copies.
