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 beed machine weed and quadratic one-way information deficits.We first provide a brief review of these measures, showing that the last ones can b
