(I wrote this article nine years ago. I still feel the same way about quantum computing. In my view, QC is nothing but a scientific fraud and a scam. Sorry.)
Part I, II
Paul Feyerabend, the foremost science critic of the last century, once wrote in his book 'Against Method' that "the most stupid procedures and the most laughable results in their domain are surrounded with an aura of excellence. It is time to cut them down in size, and to give them a more modest position in society." Feyerabend was speaking of scientists in general but he may as well have been talking about the new "science" of quantum computing. Quantum computing is based on the so-called Copenhagen interpretation of quantum mechanics. The idea is that the states of certain quantum properties, such as the spin of a particle, are superposed, meaning that a quantum property can have multiple states simultaneously.
The blatantly ridiculous nature of this belief has not stopped an entire research industry from sprouting everywhere in the academic community. QC researchers are making grandiose promises about magical computational powers being just around the corner in order to obtain grants and attract the attention of gullible investors while having nothing to show of practical importance. Not a week goes by without some announcement about some "progress" or "advance" in QC. It's like a magician going through all sorts of contortions without ever pulling the rabbit out of the hat. Rather than retrace their steps, a few physicists have tried to explain away the contradictions by postulating the existence of an infinite number of universes one for each quantum state. In so doing, the QC hole keeps getting deeper and deeper and words like fraud, crackpottery and hoax come to mind.
The problem with QC is not so much its laughable absurdity, but the fact that quantum physicists have no clue as to why certain quantum processes are probabilistic in the first place. Physicists love to boast that theirs is an empirical science but have no qualms believing in things that have never been observed. To them, superposition is not an interpretation or a belief but a fact. However, from my vantage point, QC is now a full-blown organized religion. In my next article, I will explain the simple reason that quantum processes are probabilistic and why quantum computing is utter nonsense or, using one of my favorite putdowns, "chicken feather voodoo physics".
