Reply to the "Comment on 'Contextuality within quantum mechanics manifested in subensemble mean values[Phys. Lett. A 373(2009)3430, arXiv:0912.3570]' "

TL;DR

This paper refutes a claim that a previous quantum contextuality effect can be reproduced by a Kochen-Specker model, clarifying the differences in experimental setups and emphasizing the original findings.

Contribution

It clarifies that a prior critique is invalid due to differences in experimental setups, reaffirming the original quantum contextuality results.

Findings

De Zela's claim is unjustified due to setup differences

The discussed setup is not equivalent to the original

Reproducibility by Kochen-Specker model is not supported

Abstract

In this reply, we point out that the claim by De Zela[2] is unjustified because the setup he discusses is \emph{not} equivalent to the setup analysed in our paper[1]. Hence his subsequent argument claiming the reproducibility of our demonstrated quantum effect of path-spin contextuality by the Kochen-Specker realist model is \emph{not} relevant.
