Some remarks on hidden variables and the EPR paradox

Diederik Aerts

The hidden variable solution to the EPR paradox proposes that correlation of measurements of entangled particles is due to variables that get decided when the entangled particles get created. It is shown that the correlation of spin measurements in Bell's form of the EPR paradox can be explained as deriving from spin of the entangled particles in the x-direction. This spin parameter is not hidden as it is included in the standard quantum mechanical formulation.

Abstract Einstein's severe critique of quantum mechanics took its ultimate form in the so‐called Einstein Podolsky Rosen (EPR) paradox. The latter remained a subject of mere dispute, until a remarkable progress was initiated in 1964 by Bell who showed that quantum mechanical correlations specific for an EPR type experiment cannot be reproduced in any local hidden—variables theory. Afterwards, realistic versions of EPR experiments have been conceived and, in fact, carried out. The objective of the present paper is to give a review of this recent exciting development, both theoretical and experimental, which reveals one of the most striking features of quantum theory, the “quantum interconnectedness of distant systems”.
