The Notion of Locality in Relational Quantum Mechanics

  title={The Notion of Locality in Relational Quantum Mechanics},
  author={Pierre Martin-Dussaud and Carlo Rovelli and Federico Zalamea},
  journal={Foundations of Physics},
The term ‘locality’ is used in different contexts with different meanings. There have been claims that relational quantum mechanics is local, but it is not clear then how it accounts for the effects that go under the usual name of quantum non-locality. The present article shows that the failure of ‘locality’ in the sense of Bell, once interpreted in the relational framework, reduces to the existence of a common cause in an indeterministic context. In particular, there is no need to appeal to a… 
Comment on “The Notion of Locality in Relational Quantum Mechanics”
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
What Ontology for Relational Quantum Mechanics? 1
In this paper, we evaluate some proposals that can be advanced to clarify the ontological consequences of Relational Quantum Mechanics. We first focus on priority monism and ontic structural realism
The Relational Interpretation of Quantum Physics
The relational interpretation (or RQM, for Relational Quantum Mechanics) solves the measurement problem by considering an ontology of sparse relative events, or facts. Events are realized in
Assessing Relational Quantum Mechanics
Relational Quantum Mechanics (RQM) is a non-standard interpretation of quantum theory based on the idea of abolishing the notion of absolute states of systems, in favor of states of systems relative
A Quintet of Quandaries: Five No-Go Theorems for Relational Quantum Mechanics
Relational quantum mechanics (RQM) proposes an ontology of relations between physical systems, where any system can serve as an ‘observer’ and any physical interaction between systems counts as a
Wigner’s friend and Relational Quantum Mechanics: A Reply to Laudisa
Relational Quantum Mechanics is an interpretation of quantum mechanics proposed by Carlo Rovelli. Rovelli argues that, in the same spirit as Einstein’s theory of relativity, physical quantities can
The Relational Interpretation
The relational interpretation (or RQM, for Relational Quantum Mechanics) solves the measurement problem by considering an ontology of sparse relative facts. Facts are realized in interactions between
An attempt to understand relational quantum mechanics
. We search for a possible mathematical formulation of some of the key ideas of the relational interpretation of quantum mechanics and study their consequences. We also briefly overview some proposals
QBism and Relational Quantum Mechanics compared
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
A reply to Rovelli's response to our"Assessing Relational Quantum Mechanics''
In a recent paper, Rovelli responds to our critical assessment of Relational Quantum Mechanics (RQM). His main argument is that our assessment lacks merit, because we fail to understand, or cope


Relational quantum mechanics
I suggest that the common unease with taking quantum mechanics as a fundamental description of nature (the “measurement problem”) could derive from the use of an incorrect notion, as the unease with
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
Relational EPR
It is argued that these EPR-type correlations do not entail any form of “non-locality”, when viewed in the context of this interpretation of quantum mechanics, and the abandonment of strict Einstein realism implied by the relational stance permits to reconcile quantum mechanics.
The Problem of Hidden Variables in Quantum Mechanics
Forty years after the advent of quantum mechanics the problem of hidden variables, that is, the possibility of imbedding quantum theory into a classical theory, remains a controversial and obscure

A short fresh presentation and update on the relational perspective on the theory of quantum mechanics, and a comment on its philosophical implications are given.
In this paper, we shall show how the theory of measurements is to be understood from the point of view of a physical interpretation of the quantum theory in terms of hidden variables developed in a
Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?
Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that one is led to conclude that the description of reality as given by a wave function is not complete.
The reality of relations
Discussing the contemporary debate about the metaphysics of relations and structural realism, I analyse the philosophical significance of relational quantum mechanics (RQM). Relativising properties
The Principle of the Common Cause
The common cause principle says that every correlation is either due to a direct causal effect linking the correlated entities or is brought about by a third factor, a so-called common cause. The
