- Distribution of Mutual Information in Multipartite States Jonas Maziero Física, Astronomía y Matemáticas Residual correlations Generalized monogamy relations Relative entropy of total correlation Distribution of multipartite correlations Using the relative entropy of total correlation, we derive an expression relating the mutual information of n-partite pure states to the sum of the mutual informa- tions and entropies of its marginals and analyze some of its implications. Besides, by utilizing the extended strong sub- additivity of von Neumann entropy, we obtain generalized monogamy relations for the total correlation in three-partite mixed states. These inequalities lead to a tight lower bound for this correlation in terms of the sum of the bipartite mutual informations. We use this bound to propose a mea- sure for residual three-partite total correlation and discuss the non-applicability of this kind of quantifier to measure genuine multiparty correlations. 2014 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46431122002 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2-3 Vol.44
