Recovering part of the boundary between quantum and nonquantum correlations from information causality

Abstract

Recently, the principle of information causality has appeared as a good candidate for an information-theoretic principle that would single out quantum correlations among more general nonsignaling models. Here, we present results going in this direction, namely, we show that part of the boundary of quantum correlations actually emerges from information causality. © 2009 The American Physical Society.
