Einstein-Bohr controversy and theory of hidden variables

TL;DR

This paper argues that hidden-variable theories, rather than Copenhagen quantum mechanics, better explain quantum phenomena, emphasizing differences in causality, chance, and locality, and clarifying the nature of hidden variables.

Contribution

It revisits and supports Einstein's view that hidden-variable theories are preferable, clarifies their differences from Copenhagen quantum mechanics, and discusses their ability to represent physical reality.

Findings

Hidden-variable theories align with Einstein's arguments.

Differences between hidden variables and Copenhagen interpretation are clarified.

Hidden variables can represent the properties of known physical reality.

Abstract

It has been shown by us recently that Einstein was right in his controversy with Bohr or that the so called hidden-variable theory should be preferred to the Copenhagen quantum mechanics. In the following paper the corresponding arguments will be shortly repeated. The main attention will be then devoted to explaining main differences between these two quantum alternatives, differing in the access to the problem of chance, causality and locality of microscopic objects. The actual meaning of the mentioned hidden variables will be discussed, too, the essence of which remained practically unclear during all past discussions. It will be shown that the theory of hidden variables (or Schroedinger equation alone) is able to represent the properties of the whole known physical reality.
