This paper shows that ordinary quantum mechanics is not consistent with the superluminal transmission of classical information.
Since Bell's theorem, it is known that quantum correlations cannot be described by local variables (LV) alone: if one does not want to abandon classical mechanisms for correlations, a superluminal form of communication among the particles…
