Characterization of nonsignaling correlations from mutual information

We present a characterization of the set non-signaling correlations in terms two dimensional representation that involves maximal value Bell functional and mutual information between parties. In particular, we apply this to bipartite scenario with measurements outcomes. these physically meaningful quantities through numerical optimization methods some analytical results, investigate frontier different subsets correlations, focussing on quantum post-quantum ones. Finally, show Tsirelson bound appears as singular point context without resorting mechanics.
