Abstract:

The correlations achievable between distant observers living in a quantum universe exhibit a very peculiar correlation structure. Different authors have tried to capture this structure through reasonable physical principles; the working hypothesis being that "the world is quantum not by chance, but because there is just no other way". To counter this claim, in this talk I will introduce the almost quantum set, a theoretical set of multipartite supra-quantum correlations. The almost quantum set is not only physically consistent, but also happens to satisfy all physical principles proposed so far to single out the set of quantum correlations. My results therefore suggest that our world might not be quantum after all.
