Quantum Discord and Information Deficit in Spin Chains

Quantum Discord and Information Deficit in Spin Chains

We examine the behavior of quantum correlations of spin pairs in a finite anisotropic XY spin chain immersed in a transverse magnetic field, through the analysis of the quantum discord and the conventional and quadratic one-way information deficits. We first provide a brief review of these measures,...
