Abstract

Entanglement and nonlocality are intrinsically related concepts, parts of a complex relationship that still requires better understanding. One of the scenarios that are yet to be better explored in the investigation of this relationship is the one that involves many copies of a quantum system, shared in a network. In such scenarios, it is possible to activate the nonlocality of entangled states that, in simpler scenarios, lead to local correlations only. The goals of this project are to investigate quantum networks and to obtain novel examples of activation of nonlocality.(AU)
