The CHSH Test Can be Used for All Quantum-Describable Systems

Abstract

This paper shows that the ClauserHorneShimonyHolt test of locality of correlations which was originally designed to be used with binary observables can actually be used for any couples of quantum-like bounded continuous observables, and then for any experimental situation describable within the mathematical framework of quantum theory.

  1. 1.

    For discrete spectrum observables, the integral symbol is replaced by a discrete sum over the corresponding λα and λβ.
