    "abstract": "We introduce an all-versus-nothing proof of impossibility of\nEinstein-Podolsky-Rosen\u0027s local elements of reality for two photons entangled\nboth in polarization and path degrees of freedom, which leads to a Bell\u0027s\ninequality where the classical bound is 8 and the quantum prediction is 16. A\nsimple estimation of the detection efficiency required to close the detection\nloophole using this proof gives eta \u003e 0.69. This efficiency is lower than that\nrequired for previous proposals.",
