Solving the Einstein-Podolksy-Rosen puzzle: a possible origin of non-locality

TL;DR

This paper proposes a mechanism based on photon phase during propagation to explain the non-local correlations observed in Bell-type experiments, suggesting these are not truly non-local effects but originate from a common source.

Contribution

It introduces a novel explanation for quantum non-locality using photon phase differences, challenging the conventional view of non-locality in quantum mechanics.

Findings

Photon pairs' non-local correlations stem from their common origin.

The phase difference at the source explains measurement correlations.

No signal travels faster than light in this mechanism.

Abstract

So far no mechanism is known, which could connect the two measurements in a Bell-type experiment with a speed beyond the speed of light, commonly considered the ultimate limit of propagation of any field-like interaction. Here, we suggest such a mechanism, based on the phase of a photon field during its propagation. We show that two measurements, corresponding to two independent rotations of the fields, are connected, 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.
