Test of Local Realism into the Past without Detection and Locality Loopholes
Test of Local Realism into the Past without Detection and Locality Loopholes
Inspired by the recent remarkable progress in the experimental test of local realism, we report here such a test that achieves an efficiency greater than (78%)^{2} for entangled photon pairs separated by 183 m. Further utilizing the randomness in cosmic photons from pairs of stars on the opposite sides of …
