Uniform Quantification of Correlations for Bipartite Systems (1704.03990v1)
Published 13 Apr 2017 in quant-ph
Abstract: Based on the relative entropy, we give a unified characterization of quantum correlations for nonlocality, steerability, discord and entanglement for any bipartite quantum states. For two-qubit states we show that the quantities obtained from quantifying nonlocality, steerability, entanglement and discord have strictly monotonic relationship. As for examples, the Bell diagonal states are studied in detail.
