TESTS OF QUANTUM MECHANICS AGAINST A SIMPLE FAMILY OF LOCAL HIDDEN-VARIABLES MODELS VIA POLARIZATION CORRELATION EXPERIMENTS
The quantum prediction for the polarization correlation of a general two-photon state (e.g. non-maximally entangled) is derived taking into account the non-ideal behavior of polarization analyzers and detectors. A simple family of local hidden-variables models is defined and the possible discrimination between that family and quantum mechanics is discussed.
