Quantum Locality

TL;DR

This paper clarifies that quantum nonlocality arises from classical misapplications and affirms Einstein locality as consistent with quantum mechanics, resolving apparent conflicts with relativity.

Contribution

It argues that quantum nonlocal influences are due to classical misconceptions and confirms Einstein locality as a valid principle within quantum theory.

Findings

Quantum nonlocality results from classical misapplications.

Einstein locality remains valid in quantum mechanics.

No conflict exists between quantum theory and relativity.

Abstract

It is argued that while quantum mechanics contains nonlocal or entangled states, the instantaneous or nonlocal influences sometimes thought to be present due to violations of Bell inequalities in fact arise from mistaken attempts to apply classical concepts and introduce probabilities in a manner inconsistent with the Hilbert space structure of standard quantum mechanics. Instead, Einstein locality is a valid quantum principle: objective properties of individual quantum systems do not change when something is done to another noninteracting system. There is no reason to suspect any conflict between quantum theory and special relativity.
