Maximum Observable Correlation for a Bipartite Quantum System

Hall, Michael; Andersson, Erika; Brougham, Thomas

Description

The maximum observable correlation between the two components of a bipartite quantum system is a property of the joint density operator, and is achieved by making particular measurements on the respective components. For pure states it corresponds to making measurements diagonal in a corresponding Schmidt basis. More generally, it is shown that the maximum correlation may be characterized in terms of a correlation basis for the joint density operator, which defines the corresponding...[Show more]
