Contribution

It introduces a simple local hidden variables model that aligns with experimental data, questioning the universality of quantum predictions.

Findings

The experiment shows violation of Bell inequalities.

A local hidden variables model fits the experimental data.

Quantum predictions are challenged by the model.

Abstract

A recent experiment by Brida et al. (arXiv:0705.0439 [quant-ph]) is analyzed with the conclusion that is shows a violation of standard quantum predictions. A simple local hidden variables model is studied which is compatible with the empirical results and fits fairly well the deviation from the quantum predictions.
