Unifying Treatment of Discord via Relative Entropy

Lin Zhang, Shao-Ming Fei and Jun Zhu


We study the monotonicity inequality of relative entropy under completely positive linear maps. 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.
