 The experiment of Tittel, Brendel, Zbinden, and Gisin (1998) did not directly address the communication loophole but threw some light indirectly on this question and also provided dramatic evidence concerning the maintenance of entanglement between particles of a pair that are well separated. Pairs of photons were generated in Geneva and transmitted via cables with very small probability per unit length of losing the photons to two analyzing stations in suburbs of Geneva, located 10.9 kilometers apart on a great circle. The counting rates agreed well with the predictions of quantum mechanics and violated the CHSH inequality. No precautions were taken to ensure that the choices of orientations of the two analyzers were events with space-like separation. The great distance between the two analyzing stations makes it difficult to conceive a plausible scenario for a conspiracy that would violate Bell’s independence conditions. Furthermore — and this is the feature which seems most to have captured the imagination of physicists — this experiment achieved much greater separation of the analyzers than ever before, thereby providing a test of a conjecture by Schrödinger (1935) that entanglement is a property that may dwindle with spatial separation. More recently, Bell inequality violation was demonstrated even at 144 km distance (Scheidl et al., 2010) and, in 2017, from satellite transmission with a 1200 km distance (Yin et al., 2017).
