WebJan 7, 2024 · With the following reasoning we can demonstrate it quite easily: 2000 CPS correspond to an average time interval between a photon and the next of about 0.5 ms. … WebSep 1, 2024 · We report the experimental observations of Bell inequality violations (BIV) in entangled photons causally separated by a rotating mirror. A Foucault mirror gating geometry is used to causally isolate the entangled photon source and detectors. We report an observed BIV of CHSH-S=2.30±0.07>2.00. This result rules out theories that explain …
