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. _ David Lochrin_ _______________________________________________ Link mailing list [email protected] https://mailman.anu.edu.au/mailman/listinfo/link
