When are quantum systems operationally independent?

Quantum Physics 2010-11-09 v2 Mathematical Physics math.MP

Abstract

We propose some formulations of the notion of "operational independence" of two subsystems of a larger quantum system 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.
