A local hidden-variable model violating Bell's inequalities: a reply to Matzkin

TL;DR

This paper critiques Matzkin's claim of a local hidden-variable model matching quantum predictions, arguing that an overlooked non-local element invalidates its locality.

Contribution

It provides a detailed analysis showing that Matzkin's model is not truly local due to an unacknowledged non-local hidden variable.

Findings

Matzkin's model claims to be local and quantum-equivalent.

Identification of a non-local hidden variable in the model.

The model's locality is invalidated by this non-local element.

Abstract

Recently, Matzkin claimed the construction of a hidden variable (HV) model which is both local and equivalent with the quantum-mechanical predictions. In this paper we will briefly present this HV model and argue, by identifying an extra non-local "hidden" HV, why this model is not local
