Bell theorem and its generalization: From foundations to applications

Abstract: Quantum correlations are obtained when multiple parties perform independent measurements on a shared quantum state. Bell’s seminal theorem proves that certain correlations predicted by quantum theory resist explanations in terms of any Local Hidden Variable theory based on shared randomness. I’ll first review the Bell theorem, its main foundational consequences and some of its applications. Then, I will discuss recent generalization of this theorem in the context of causal quantum networks, in which now multiple parties perform independent measurements on several, independent quantum states.
