Maximal mutual correlation: an algebraic measure of correlations in bipartite quantum systems

Quantum Physics 2016-07-25 v1

Abstract

We introduce an algebraic measure of correlations in bipartite quantum systems. The proposed quantity, called maximal mutual correlation, provides the information how much a given state differs from the product state of its marginals. In contrast to the entanglement or quantum discord, maximal mutual correlation can be non - zero for some classically correlated quantum states.
