Two copies of the Einstein-Podolsky-Rosen state of light lead to refutation of EPR ideas.
Bell's theorem applies to the normalizable approximations of original Einstein-Podolsky-Rosen (EPR) state. The constructions of the proof require measurements difficult to perform, and dichotomic observables. By noticing the fact that the four mode squeezed vacuum state produced in type II down-conversion can be seen both as two copies of approximate EPR states, and also as a kind of polarizati...
متن کاملA minimal state-dependent proof of measurement contextuality for a qubit
The doubts of EPR [1] and the theorems of Bell, Kochen and Specker [2, 3, 4] established the impossibility of some very natural hidden variable models of quantum theory, characterized by locality and noncontextuality. Spekkens recently generalized this class of models to generalizednoncontextual ontological models, defining them in a manner that is applicable to any operational theory rather th...
متن کاملEPR anomalies, \photon" amplitudes and Malus' Law: an intuitive classical approach
Observation shows that, to a very close approximation, real polarisers and photomultipliers reproduce Malus' Law even at the \single photon" level, giving a sinusoidal variation of \photon" count with polarisation angle. At rst sight, this appears to rule out various realist models of polarisers and detectors, and casts doubt on their ability to explain \paired-photon" EPR experiments. The obse...
متن کاملBell Locality and the Nonlocal Character of Nature
It is demonstrated that hidden variables of a certain type follow logically from a certain local causality requirement (“Bell Locality”) and the empirically well-supported predictions of quantum theory for the standard EPR-Bell setup. The demonstrated hidden variables are precisely those needed for the derivation of the Bell Inequalities. We thus refute the widespread view that empirical violat...
متن کاملComplete account of randomness in the EPR-Bohm-Bell experiment
We show that paradoxical consequences of violations of Bell’s inequality are induced by the use of an unsuitable probabilistic description for the EPR-Bohm-Bell experiment. The conventional description (due to Bell) is based on a combination of statistical data collected for different settings of polarization beam splitters (PBSs). In fact, such data consists of some conditional probabilities w...
