Nobel Prize for physics in 2022 goes to Alain Aspect, John F. Clauser, and Anton Zeilinger for their experiments with entangled photons which proved what Einstein once described as “spooky action at a distance”. Anton Zeilinger got his price for his quantum teleportation experiments that you can verify nowadays on a quantum computer over the cloud.
By the way, the spooky action at a distance for entangled photons (i.e. the fact that measuring the polarization of one photon of an entangled pair immediately determines the polarization state of the second photon, no matter of how far the photons are apart, so that there is no possibility that the measurement result can be transferred from the first to the second photon with speed of light) finds a simple explanation in Hugh Everett’s many-worlds interpretation of quantum mechanics that was proposed in 1957, two years after Einstein’s death. Following to this interpretation, with the act of measurement the observer finds himself in a world (of the many worlds) that is consistent with the measurement of the first photon. Thus this observer, who is also a macroscopic quantum object, can only measure this consistent value for the second photon.
