Quantum Physics


Retrospective Examination of Three Articles Published in the Revue Des Questions Scientifiques in 2005 and 2006.

Authors: François Barriquand

Three articles published by the same author in the Revue des Questions Scientifiques in 2005 and 2006 are reexamined with special attention paid to a theorem published by Allahverdyan and Nieuwenhuizen in 2002 concerning Thomson's formulation of the second law, as well as to the results of the so-called "before-before" experiment performed on entangled pairs by Stefanov, Zbinden, Gisin and Suarez. As far as thermodynamics are concerned, it is explained here that a macroscopic observer can generate quasi "cycles", whose cyclical characteristics are in fact only valid from the macroscopic point of view, that can potentially enable her/him to retrieve work from a thermalizer without causing any perpetual motion. Concerning quantum entanglement, it is recognized - in contrast with what the author originally published in 2005 and 2006 - that superluminal transmission of decipherable information cannot be achieved if the Copenhagen interpretation of quantum theory remains universally valid. It is also pointed out that the foundations of general relativity cannot be easily reconciled with the implications of Einstein-Podolsky-Rosen measurements.
