Relational Quantum Mechanics and Contextuality

TL;DR

This paper explores how the consistent histories formalism can clarify information sharing in Relational Quantum Mechanics, proposing integration of the mathematical framework to enhance interpretational clarity and discussing related issues like relativity.

Contribution

It introduces the incorporation of the consistent histories formalism into RQM, clarifying the sharing of information and addressing interpretational differences.

Findings

Consistent histories can clarify information sharing in RQM

Mathematical framework integration enhances interpretational clarity

Discusses similarities between RQM and special relativity

Abstract

This paper discusses the question of Stable Facts in Relational Quantum Mechanics. I examine how the approach to quantum logic in the consistent histories formalism can be used to clarify what information about a system can be shared between different observers.I suggest that the mathematical framework for Consistent Histories can and should be incorporated into RQM, whilst being clear on the interpretational differences between the two approaches. Finally I briefly discuss two related issues: the similarities and differences between special relativity and RQM and the recent Cross- Perspectival Links modification to RQM.
