Comment on `The notion of locality in relational quantum mechanics'

TL;DR

This paper critically examines a recent analysis of Bell's local causality in relational quantum mechanics, arguing that the implications of the relational interpretation are more radical than previously concluded.

Contribution

It challenges the conclusion that quantum violations of Bell's local causality are unsurprising, emphasizing the more profound implications of the relational interpretation.

Findings

Relational interpretation implies more radical consequences than previously acknowledged.

The critique questions the adequacy of the recent analysis of Bell's locality.

The paper emphasizes the need to reconsider the implications of relational quantum mechanics.

Abstract

A recent paper [P. Martin-Dussaud, C. Rovelli, F. Zalamea, arXiv:1806.08150] has given a lucid treatment of Bell's notion of local causality within the framework of the relational interpretation of quantum mechanics. However, the authors went on to conclude that the quantum violation of Bell's notion of local causality is no more surprising than a common cause. Here, I argue that this conclusion is unwarranted by the authors' own analysis. On the contrary, within the framework outlined by the authors, I argue that the implications of the relational interpretation are much more radical.
