Revised Definitions of Quantum Dissonance and Quantum Discord
arXiv:1011.4333
Abstract
We show that all the correlations defined by K. Modi et al [Phys. Rev. Lett. {\bf 104}, 080501 (2010)] except for the total mutual information should be redefined so that some physical quantities (e.g., the accessible maximal classical correlation and the resultant exact quantum discord) are right.
