A Note on the Geometric Interpretation of Bell's Inequalities

Paolo Dai Pra, Michele Pavon, Neeraja Sahasrabudhe

Research output: Contribution to journalArticlepeer-review


Using results of Pitowsky and Gupta, we show in a direct, elementary fashion that, in the case of three spins, Bell's inequalities indeed provide a representation of the tetrahedron of all spin correlation matrices as intersection of half-spaces.
