#### Re: A solution without a problem

...not only **rather** recursive, but definitely recursive, a tautology ("Quantum computers can solve those problems that, um, only a quantum computer can solve."(!)). The very valid argument against quantum computers is the same as that which applies to any pseudoscience: **the concept is not falsifiable**. This is precisely what is wrong with the statements--and very hard work--of some extremely sincere people regarding such things as fusion power to solve all our energy problems ("Oh, so what you're proposing is that we simply build a **miniature sun, right here on earth** to solve all our problems ‽ Sounds good to me; we'll get right on it. Oh, and I'll only need several millions of dollars to get started, and to continue. Gee, thanks; I knew you'd understand..." ); and Superstring Theory, which would only require more energy than what's available in the observable universe to prove...or disprove.

Ask anyone who *professes* to be a Q-C 'expert' two simple questions: (1) In terms, which any Electrical and Computer Engineer can understand, how does one build a Quantum Computer?, and (2) demonstrate (same conditions) how one programs a Quantum Computer. It has been proven time and time again that your answer(s) will consist of nothing more than what can be charitably described as 'arm-waving' and 'tap-dancing'.

The Quantum Computer is a problem looking for a problem; which, unfortunately, is going to suck a lot of resources away from valid, tractable problems and efforts which definitely need addressing and for which there exists a reasonable chance of solving. Quantum Computing meets none of these criteria. Simply start with the "...valid problem..." point. One needs go no further.
