Einstein's firm belief in physical reality was expressed in a 1935 paper, the last important one in his career. Although it prompted Schrödinger to invent his celebrated Cat, the paper was at first largely ignored. Still, it led to a 40-year chain of contributions to the current understanding of quantum theory. Even now, however, not all active physicists agree about the correct understanding of the distinction between Einstein's reality and the kind of reality that is available via quantum theory. A set of so-called Bell Inequalities, proven by John Bell in the 1960s, play a role in almost all discussions of the quantum-classical boundary zone (if there is such a zone). The talk will focus on simple examples of Bell Inequalities and their consequences in a model of some simple optical laboratory tests. These were invented and carried out by John Clauser in 1972 and were followed and extended by Alain Aspect in 1982. The tests became famous because one can say that they show photons to be immune to Bell's mathematically rigorous proof. (Click aquí para ver el afiche.)
