Bell inequality for arbitrary many settings of the analyzers

Quantum Physics 2009-10-31 v1

Abstract

A generalization of the CHSH-Bell inequality to arbitrary many settings is presented. The singlet state of two spin \half\half violates this inequality for all numbers of setting. In the limit of arbitrarily large number of settings, the violation tends to the finite ratio 4/π1.274/\pi \approx 1.27.
