The Locality Problem in Quantum Measurements

TL;DR

This paper addresses the locality problem in quantum measurements, demonstrating that the algebraic formalism of quantum theory can be compatible with a local physical reality, and offers new interpretations of key quantum experiments.

Contribution

It shows that the algebraic approach allows reconciling quantum formalism with local realism, challenging widespread assumptions about nonlocality in quantum mechanics.

Findings

Reconciliation of quantum formalism with local realism.

Physical interpretation of key experiments consistent with classical ideas.

Analysis of experiments like EPR and teleportation from a locality perspective.

Abstract

The locality problem of quantum measurements is considered in the framework of the algebraic approach. It is shown that contrary to the currently widespread opinion one can reconcile the mathematical formalism of the quantum theory with the assumption of the existence of a local physical reality determining the results of local measurements. The key quantum experiments: double-slit experiment on electron scattering, Wheeler's delayed-choice experiment, the Einstein-Podolsky-Rosen paradox, and quantum teleportation are discussed from the locality-problem point of view. A clear physical interpretation for these experiments, which does not contradict the classical ideas, is given.
