Local computer model emulating the results of the Pan et al. experiment

TL;DR

This paper presents a local computer simulation model that replicates quantum experiment results, challenging the belief that local models cannot explain such phenomena, and critiques previous local models' reasoning.

Contribution

The authors develop a computer-based local model that accurately reproduces quantum correlations, demonstrating that local explanations are feasible and questioning prior assumptions.

Findings

The simulation matches quantum correlations better than actual experiments.

Previous local models contained flawed reasoning affecting their validity.

Local models can, in principle, replicate quantum experiment results.

Abstract

It is a widespread current belief that objective local models can not explain the quantum optics experiment of Pan et al. By presenting a model that operates on independent computers, we show that this belief is unfounded. Three remote computers (Alice, Bob and Claire), that never communicate with each other, send measurement results to a fourth computer that is in charge of collecting the data and computing correlations. The result obtained by our local simulation is in better agreement with the ideal quantum result than the Pan et al. experiment. We also show that the local model presented by Pan et al. that can not explain the quantum results contains inappropriate reasoning with profound consequences for the possible results of any local model that uses probability theory.
