I discuss a remarkable answer to this question proposed by Pawlowski et al (2009), who provide an information-theoretic derivation of the Tsirelson bound from a principle they call {\textquoteright}information causality.{\textquoteright} }, doi = {10.1007/978-3-642-21329-8_11}, url = {http://arxiv.org/abs/1208.3744v1}, author = {Jeffrey Bub} }
