Total correlations and mutual information
arXiv:0806.4861 · doi:10.1016/j.physleta.2009.03.047
Abstract
In quantum information theory it is generally accepted that quantum mutual information is an information-theoretic measure of total correlations of a bipartite quantum state. We argue that there exist quantum states for which quantum mutual information cannot be considered as a measure of total correlations. Moreover, for these states we propose a different way of quantifying total correlations.
