Entangled states explained locally — •Eugen Muchowski — Primelstrasse 10, 85591 Vaterstetten

The existence of entangled states (Bell states) forces us to reconsider our conception of physical reality. This is best done using a model. However, after Bell's theorem a local realistic model describing the quantum correlations should not exist. But Bell's theorem has been refuted by a contextual model. So we are able to concretely discuss terms like contextuality, indistinguishability, inseparability and counterfactual definiteness using a local realistic model. We introduce a model in which the indistinguishability of the entangled photons explains the physical states, but in which the photon pairs do not share the value of a statistical parameter. It is astonishing that a model of entangled quantum systems can be derived solely from the initial conditions and the assumption that the behaviour of quantum particles is determined in advance. No coupling of hidden parameters is required.
