A critical analysis of `Relative facts do not exist. Relational quantum mechanics is incompatible with quantum mechanics' by Jay Lawrence, Marcin Markiewicz and Marek \'{Z}ukowski

TL;DR

This paper critically examines and refutes recent claims that relational quantum mechanics is incompatible with quantum mechanics, providing a detailed rebuttal to the arguments based on GHZ nonlocality theorems.

Contribution

The authors offer a thorough critique of recent criticisms against RQM, clarifying misconceptions and defending the consistency of RQM with quantum mechanics.

Findings

The recent critique of RQM is unjustified.

The analysis of GHZ nonlocality does not invalidate RQM.

The authors successfully defend RQM's compatibility with quantum mechanics.

Abstract

We discuss a recent work by J.~Lawrence et al.[arxiv.org/abs/2208.11793] criticizing relational quantum mechanics (RQM) and based on a famous nonlocality theorem Going back to Greenberger Horne and Zeilinger (GHZ). Here, we show that the claims presented in this recent work are unjustified and we debunk the analysis.
