Bell inequalities for a sensible family of local hidden variable theories testable at low detection efficiency

Quantum Optics and Quantum Information

Abstract.

A family of local models containing two angles as hidden variables is defined for experiments measuring polarization correlation of optical photons. Searching for the best model of the family, that is giving predictions most close to quantum mechanics, allows deriving Bell-type inequalities which may be tested with relatively low detection efficiency.
