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 … WebA study in 2014 pointed out that, in a manner of speaking, we all can see infrared photons, too. If two infrared photons smack into a retinal cell nearly simultaneously, their energy …
