A Critical Analysis of the Quantum Nonlocality Problem: On the Polemic Assessment of What Bell Did

Despite their Nobel prize-winning empirical verification, the interpretation of the Bell inequality remains controversial. The alleged nonlocal character of quantum mechanics is inextricably related to the formulation of the Bell theorem. However, as is usually presented, the relation disagrees with Bell's approach and is inappropriately posed. The departure from the clear line of reasoning that Bell tried to convey has contributed to a polarization of part of the scientific community. We review part of Bell's work and show how the correct appreciation of Bell's rationale calls for reformulating a widespread argument on quantum nonlocality, yielding a more balanced perspective of the problem. We highlight a more formal proof of quantum mechanics' violation of local causality. For completeness, we mention a few alternatives that may justify considering quantum mechanics as a local theory.

We review John Stewart Bell's works from a historical perspective and analyze his arguments regarding nonlocality as he developed them from 1964 until his sudden and unexpected death in 1990. Although the alleged nonlocal character of quantum mechanics is inextricably related to the formulation of the Bell theorem, that relation is usually inappropriately posed and disagrees with Bell's own formulation. The departure from the clear line of reasoning that Bell tried to convey has contributed to a polarization of part of the scientific community into radical irreconcilable positions. We show how the correct appreciation of Bell's rationale calls for reformulating a widespread argument on quantum nonlocality yielding a more balanced perspective of the problem. We highlight a more formal proof of quantum mechanics' violation of local causality. Finally, we mention a few alternatives that may justify considering quantum mechanics as a local theory.

The Evolution of the Bell Notion of Beable: From Bohr to Primitive Ontology

John S. Bell introduced the notion of beable, as opposed to the standard notion of observable, in order to emphasize the need for an unambiguous formulation of quantum mechanics. In the paper I show that Bell formulated in fact two different theories of beables. The first is somehow reminiscent of the Bohr views on quantum mechanics but, at the same time, is curiously adopted by Bell as a critical tool against the Copenhagen interpretation, whereas the second, more mature formulation was among the sources of inspiration of the so-called Primitive Ontology (PO) approach to quantum mechanics, an approach inspired to scientific realism. In the first part of the paper it is argued that, contrary to the Bell wishes, the first formulation of the theory fails to be an effective recipe for addressing the ambiguity underlying the standard formulation of quantum mechanics, whereas it is only the second formulation that successfully paves the way to the PO approach. In the second part, I consider how the distinction between the two formulations of the Bell theory of beables fares vis-a-vis the complex relationship between the theory of beables and the details of the PO approach.

On the Meaning of Local Realism

Abstract: We analyze the different meanings currently assigned to the term "local realism" in the context of the conceptual and empirical violations of Bell-type inequalities. We point out that most of them are inconsistent and propose a possible correct connotation.
