Comment on "Lower Bound on the Speed of Nonlocal Correlations without Locality and Measurement Choice Loopholes"

TL;DR

This paper critically analyzes a recent claim about closing the locality loophole in nonlocal correlation experiments, highlighting counter-examples and issues in the original work's space-time diagrams.

Contribution

The paper provides a critical commentary identifying flaws and counter-explanations that challenge the claim of closing the locality loophole in the referenced study.

Findings

Identifies two local explanations contradicting the claim

Highlights problems in the original space-time diagrams

Argues that the claim of closing the loophole is not substantiated

Abstract

The authors claim that they "strictly" closed locality loophole, but their work does not close the locality loophole. there are at least two local transinformation explanations. The two explanations are the counter-examples of their claim. No reason can make a conclusion be right when there are counter-examples of the conclusion. And the two explanations also illustrate that the space-time diagrams of the paper have at least two problems.
