Abstract

Nonlocality is one of the fascinating features of quantum mechanics. In particular, Bell's nonlocality completely changes our understanding of locality in physics and correlations in nature. In this talk, first Bell's nonlocality and its consequences in algorithms and complexity theory is reviewed. Then the general problem of nonlocality in networks is introduced. A main question here is whether network nonlocality results is correlations beyond Bell's setting or not. This question is answered affirmatively by presenting an explicit example in the triangle network. This talk is based on joint works with Marc-Olivier Renou, Yuyi Wang, Elisa Baumer, Sadra Boreiri, Nicolas Brunner and Nicolas Gisin. No particular knowledge of quantum mechanics is required to follow this talk.
