E.P.R.-Type Experiments and Enhanced Photon Detection
Local realistic models exist which reproduce the quantum mechanical predictions for single photons and approximate closely the quantum mechanical predictions for pairs of correlated photons; in these models the quantum efficiency is interpreted as a true average of detection probabilities different from photon to photon. A large set of local realistic models with enhanced photon detection is discussed. In these models the apparent violations of locality arise from polarization correlations estabilished in the detectors. This means that the introduction of a third polarizer gives rise to different results from ordinary quantum theory. The numerical values of such effects in the case of real experimental apparatuses (Strirling, Catania) is estabilished.
