A lower bound for the velocity of quantum communications in the preferred frame
arXiv:1006.2697 · doi:10.1016/j.physleta.2010.10.064
Abstract
An EPR experiment with polarized entangled photons is performed to test the Eberhard model. According to the Eberhard model, quantum correlations between space-like separated events are due to a superluminal communication signal propagating in a preferred frame. The coincidences between entangled photons passing through two polarizers aligned along a East-West axis are measured as a function of time during 21 sidereal days. No deviation from the predictions of the Quantum Theory is observed. Tacking into account for the experimental uncertainties, we infer that, if a preferred frame for superluminal signals exists which moves at velocity \vec{v} with respect to the Earth, the modulus of the velocity of quantum communications in this frame has to be greater than v_{t}~0.6*10^4 c for v<0.1 c and for any arbitrary direction of \vec{v}.
