# Relational Quantum Mechanics and the Determinacy Problem

@article{Brown2009RelationalQM, title={Relational Quantum Mechanics and the Determinacy Problem}, author={Matthew J. Brown}, journal={The British Journal for the Philosophy of Science}, year={2009}, volume={60}, pages={679 - 695} }

Carlo Rovelli's relational interpretation of quantum mechanics holds that a system's states or the values of its physical quantities as normally conceived only exist relative to a cut between a system and an observer or measuring instrument. Furthermore, on Rovelli's account, the appearance of determinate observations from pure quantum superpositions happens only relative to the interaction of the system and observer. Jeffrey Barrett ([1999]) has pointed out that certain relational…

Rovelli’s relational quantum mechanics, anti-monism and quantum becoming

In this paper I present and defend Rovelli's relation quantum mechanics (RQM) from some foreseeable objections, so as to clarify its philosophical implications vis a vis rival interpretations. In…

Open Problems in Relational Quantum Mechanics

- PhilosophyJournal for General Philosophy of Science

It is shown that it is far from clear what a relativization of states to observers exactly achieves and in what sense such an approach really advances the authors' understanding of the peculiar features of quantum phenomena, and it is argued that the claim that RQM is able to preserve locality is at best dubious.

Relational quantum mechanics (RQM) is an interpretation of quantum mechanics based on the idea that quantum states describe not an absolute property of a system but rather a relationship between…

Can We Make Sense of Relational Quantum Mechanics?

It is claimed that there is currently no adapted locality criterion to evaluate whether the resulting interpretation is local or not, and one of its central claims concerning the possibility for an observer to have knowledge about other observer’s events is clarified.

In this paper we compare the subjective Bayesian interpretation of quantum mechanics (QBism) [1–13] with Rovelli’s relational interpretation of quantum mechanics (RQM) [14–31]. Both interpretations…
