Solving the Einstein-Podolsky-Rosen puzzle: the origin of non-locality in Aspect-type experiments

TL;DR

This paper proposes a phase-based mechanism to explain the correlations observed in Aspect-type experiments, suggesting that non-locality arises from a common source rather than instantaneous signals, impacting quantum cryptography and computation.

Contribution

It introduces a novel phase-based model that explains quantum correlations without invoking true non-locality, challenging conventional interpretations.

Findings

Polarization measurements are correlated without signals passing between detectors.

The non-locality is attributed to the photon source, not instantaneous communication.

The model could influence future quantum cryptography and computation methods.

Abstract

So far no mechanism is known, which could connect the two measurements in an Aspect-type experiment. Here, we suggest such a mechanism, based on the phase of a photon's field during propagation. We show that two polarization measurements are correlated, even if no signal passes from one point of measurement to the other. The non-local connection of a photon pair is the result of its origin at a common source, where the two fields acquire a well defined phase difference. Therefore, it is not actually a non-local effect in any conventional sense. We expect that the model and the detailed analysis it allows will have a major impact on quantum cryptography and quantum computation.
