On Bell's Theorem and Quantum-Mechanically Predicted Perfect Correlations

The experimental test of the CHSH inequality confirms the quantum-mechanically predicted perfect correlations between spatially separated photons in single pairs. This paper considers two representative explanations of the correlations, Bell's theorem and Einstein's explanation. By explaining the correlations non-locally as the so-called entanglement, Bell's theorem denies the existence of definite polarizations possessed by photons in the absence of measurement. The denial amounts to refuting Einstein's argument for defending his local-realist world view in the Einstein-Bohr debate on the conceptual foundations of quantum mechanics. As shown in this paper, Bell's theorem is an erroneous explanation of the experimental results obtained by testing the CHSH inequality. It conceals the origin of the randomness exhibited in the experimental test. Einstein's explanation is based on his separability principle and his ensemble interpretation of ψ-functions. It is supported by a formal analysis. In contrast to Bell's erroneous explanation, Einstein's explanation reveals the deterministic nature of the correlations and explains the correlations reasonably.
