Unifying Treatment of Discord via Relative Entropy
arXiv:1206.4109 · doi:10.1007/s10773-012-1361-x
Abstract
A new form of zero-discord state via Petz's monotonicity condition on relative entropy with equality has been derived systematically. A generalization of symmetric zero-discord states is presented and the related physical implications are discussed.
