When are quantum systems operationally independent?

By Miklós Rédei and Stephen J. Summers

Abstract

We propose some formulations of the notion of "operational independence" of two subsystems S1,S2 of a larger quantum system S and clarify their relation to other independence concepts in the literature. In addition, we indicate why the operational independence of quantum subsystems holds quite generally, both in nonrelativistic and relativistic quantum theory
