Information-causality and extremal tripartite correlations

Abstract

We study the principle of information-causality (IC) in the presence of extremal no-signaling correlations on a tripartite scenario. We prove that all, except one, of the non-local correlations lead to violation of IC. The remaining non-quantum correlation is shown to satisfy any bipartite physical principle. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
