Can Non-Detected Photons Simulate Non-Local Effects in Two-Photon Polarization Correlation Experiments ?
The recent experiments made on the analysis of the polarizations of the two photons emitted in a radiative decay of an excited calcium atom are reviewed. From the possible biases, only that coming from a conspiracy generated by non-detected photons in the apparatus cannot be completely excluded. However, this hypothesis is found unlikely to allow the possibility of some deterministic local theory. Non-local effects predicted by quantum mechanics are thus very difficult to reject.
