Relational Quantum Mechanics and Contextuality
arXiv:2308.08922 · doi:10.1007/s10701-024-00788-0
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.
