Quantum Nonlocality: Not Eliminated by the Heisenberg Picture

TL;DR

This paper argues that the Heisenberg picture does not resolve Einstein locality issues in quantum mechanics, showing that EPR correlations exist prior to local comparison, thus challenging claims that it supports locality.

Contribution

It demonstrates that the Heisenberg picture does not eliminate nonlocal correlations, countering previous claims that it preserves locality in quantum mechanics.

Findings

EPR correlations exist before local comparison

Heisenberg picture does not save Einstein locality

Challenges previous claims of locality preservation

Abstract

It is argued that the Heisenberg picture of standard quantum mechanics does not save Einstein locality as claimed in Deutsch and Hayden (2000). In particular, the EPR-type correlations that DH obtain by comparing two qubits in a local manner are shown to exist before that comparison. In view of this result, the local comparison argument would appear to ineffective in supporting their locality claim.
