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… Expand

Comment on “The Notion of Locality in Relational Quantum Mechanics”
  • J. Pienaar
  • Philosophy, Physics
  • Foundations of Physics
  • 2019
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… Expand
Open Problems in Relational Quantum Mechanics
TLDR
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.

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… Expand
A response to the Mucino-Okon-Sudarsky's Assessment of Relational Quantum Mechanics
The problem of quantum physics is not that we have no way of making sense of it. The problem is that we have many ways of making sense of it. But each of these comes with a high conceptual price.… Expand
Reformulating Bell's theorem: The search for a truly local quantum theory
Abstract The apparent nonlocality of quantum theory has been a persistent concern. Einstein et al. (1935) and Bell (1964) emphasized the apparent nonlocality arising from entanglement correlations.… Expand
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… Expand
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… Expand
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… Expand
Switching internal times and a new perspective on the 'wave function of the universe'
Despite its importance in general relativity, a quantum notion of general covariance has not yet been established in quantum gravity and cosmology, where, given the a priori absence of coordinates,… Expand
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… Expand

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… Expand

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… Expand
Relational EPR
We study the EPR-type correlations from the perspective of the relational interpretation of quantum mechanics. We argue that these correlations do not entail any form of “non-locality”, when viewed… Expand

Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?
TLDR
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. Expand
