Comment on `Underlining some limitations of the statistical formalism in quantum mechanics' by Fratini and Hayrapetyan

TL;DR

This paper critiques Fratini and Hayrapetyan's analysis by emphasizing the importance of randomness in statistical ensembles, arguing their conclusions about quantum mechanics limitations are unfounded.

Contribution

It clarifies the role of randomness in statistical ensembles and defends the validity of standard statistical formalism in quantum mechanics.

Findings

Fratini and Hayrapetyan's analysis is irrelevant for standard ensembles.

Their conclusions about limitations of the theory are unjustified.

Highlights the necessity of randomness in statistical ensemble preparation.

Abstract

We point out that Fratini and Hayrapetyan ignored the randomness of mixing, a basic request to prepare a statistical ensemble rather than an ensemble in general. Their analysis is irrelevant for standard statistical ensembles, their conclusions about the limitations of standard theory become unjustified.
