Loophole-free Bell's experiment and two-photon all-versus-nothing violation of local realism
arXiv:quant-ph/0507260 · doi:10.1103/PhysRevA.72.050101
Abstract
We introduce an all-versus-nothing proof of impossibility of Einstein-Podolsky-Rosen's local elements of reality for two photons entangled both in polarization and path degrees of freedom, which leads to a Bell's inequality where the classical bound is 8 and the quantum prediction is 16. A simple estimation of the detection efficiency required to close the detection loophole using this proof gives eta > 0.69. This efficiency is lower than that required for previous proposals.
