What connects entangled photons? — •Eugen Muchowski — Primelstrasse 10, 85591 Vaterstetten

A local realistic model is presented which reproduces the quantum mechanical predictions for expectation values with polarization measurements, but is not based on shared statistical parameters. Instead, the coupling of the entangled particles is based on initial conditions and conservation of spin angular momentum. The model refutes Bell's theorem and also explains teleportation and entanglement swapping in a local way. It is also shown which error in Bell's derivation leads to Bell's inequality failing to correctly describe the relationships between expectation values from quantum mechanics. The consequences for quantum computing are discussed.

Keywords: entanglement swapping; teleportation; Bell's Theorem; quantum computing
