Proofs of nonlocality without inequalities revisited

TL;DR

This paper critically revisits nonlocality proofs that do not rely on inequalities, generalizes these proofs for bipartite states, and explores their connection with the Clauser-Horne inequality.

Contribution

It provides a comprehensive analysis and generalization of nonlocality without inequalities proofs and clarifies their relationship with the Clauser-Horne inequality.

Findings

Nonlocality proofs without inequalities can be generalized for bipartite states.

A detailed analysis of the relation between nonlocality proofs and the Clauser-Horne inequality.

Insights into the foundational aspects of quantum nonlocality.

Abstract

We discuss critically the so-called nonlocality without inequalities proofs for bipartite quantum states, we generalize them and we analyze their relation with the Clauser-Horne inequality.
