Correlation measures in bipartite states and entanglement irreversibility
arXiv:1110.6873 · doi:10.1103/PhysRevA.86.012329
Abstract
We derive quantitative relations among several naturally defined measures of classical and nonclassical correlations in a bipartite quantum state. We also obtain an upper bound of entanglement irreversibility and a sufficient condition for reversible entanglement. The additivity of entanglement of formation is directly related to the additivity of quantum discord as well as a certain measure of classical correlation.
