Sascha Vongehr complains on his blog: "Experts agree that solving the
Quantum Randi Challenge would deserve the Nobel Prize. However, experts also keep demanding to reformulate the challenge with a variation of the Bell inequality called 'CHSH'."
I should hope so. The experts are the ones who have studied EPR/Bell and its CHSH extension to a considerably higher standard than an unpublished arxiv paper that reads as if it were a sophomore term paper written the night of the big frat party beer bust.
Because I know Vongehr's proposal to be flawed in principle -- the idea of it bears hardly even a superficial resemblance to the real Randi challenge -- I hadn't read the paper before. Now that I have, I am even more incensed that such babble survives on the borrowed credibility and reputation of the scientific enterprise.
I went in expecting to dissect the paper and refute it point by point. It turned out to be a waste of time to even read, much less bother to refute -- Vongehr's principal notion is that "The described multi-player game computer setup constitutes a classical physical system; computers are physical! In short: if the computer setup could violate Bell's inequality, that very computer network would be a classical physical system that violates the Bell inequality and such would deserve a Nobel Prize."
This is not just laughable; it borders on the insane. Coming from one who regularly savages serious researchers as "crackpots," and recommends Prozac, it comes across to me as simply pitiful. At any rate, it is the easiest matter to refute the notion: if Vongehr understood even the first jot of Wheeler's information-theoretic program that he pretends to, he would know that it isn't computers that are physical; information is physical. Current research in complex systems -- such as that by Strogatz, et al in the small world effect, and Bar-Yam, et al in bounded rationality -- clearly show that interacting systems (even a multi-player game such as V proposes) show little change on the large scale over long time intervals. Undaunted by empirical facts and actual experimental results, though, V allows his players to win against large odds because they live in parallel worlds. Sorry, dude, we all live in the same world where even your own "peer reviewer" Richard Gill acknowledges that the law of large numbers applies equally to every case, and that experimental results must be independent of theoretical expectations.
As for this gem -- "About the equivalence of classical physics and classical computation: All experimental observations have finite resolution due to experimental errors/accuracy. The (today practically limitless) finite capacity of computer memory does therefore not present an obstacle to those who believe classical physics to involve true continuums." -- Good to know that Sascha has all the time in eternity at his disposal. Seems that he not only truncates critics to suit his whims, nature herself gets a close haircut.
There are no "true continuums." There are continua constrained by abitrary boundary conditions, and there is THE continuum. It was the continuum, singular, from which Wheeler derived quantum information, and which every mathematician distinguishes from discrete numbers.
Now if one can prove that the simulation of a continuous function is a continuous function ... no chance that Vongehr is up to it, though.
