The authors of this paper, Gregor Weihs, Thomas Jennewein, Christoph Simon, Harald Weinfurter, and Anton Zeilinger, conducted an experiment to violate Bell's inequality under strict Einstein locality conditions. They achieved this by implementing a type of Einstein-Podolsky-Rosen (EPR) experiment with independent observers, ensuring that the measurements were space-like separated and that no information could travel between the observers faster than the speed of light. The experiment used polarization-entangled photon pairs and involved spatially separated observers, Alice and Bob, who were 400 meters apart. They achieved this separation by using optical fibers and ensuring that the measurements were completed within 1.3 μs, the time for direct communication at the speed of light. The experiment used high-speed physical random number generators and fast electro-optic modulators to ensure unpredictability and independence. The results showed a strong violation of Bell's inequality, with a maximum violation of 2.82, which is significantly higher than the quantum mechanical prediction of 2.74. The authors concluded that their experiment confirmed the predictions of quantum mechanics and discussed the implications for local realistic or semi-classical interpretations.The authors of this paper, Gregor Weihs, Thomas Jennewein, Christoph Simon, Harald Weinfurter, and Anton Zeilinger, conducted an experiment to violate Bell's inequality under strict Einstein locality conditions.
