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 in the context of this interpretation. The abandonment of strict Einstein realism implied by the relational stance permits to reconcile quantum mechanics, completeness, (operationally defined) separability, and locality. 
The Relational Interpretation of Quantum Mechanics and the EPR Paradox
Bernad d’Espagnat. Most of us, of course, have heard of the new and daring interpretation of quantum mechanics proposed by Carlo Rovelli, who is here today, called Relational Quantum Mechanics.
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
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
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
The Notion of Locality in Relational Quantum Mechanics
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.
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.
The EPR paradox and the uncertainty principle
The EPR paradox appears when measurement results of some properties of two distantly entangled particles are correlated in a way that cannot be explained classically, and apparently violate localit...
The Algebra of the Pseudo-Observables II: The Measurement Problem
In this second paper, we develop the full mathematical structure of the algebra of the pseudo-observables, in order to solve the quantum measurement problem. Quantum state vectors are recovered but
The interpretation of quantum mechanics and of probability: Identical role of the 'observer'
The aim of the article is to argue that the interpretations of quantum mechanics and of probability are much closer than usually thought. Indeed, a detailed analysis of the concept of probability


The EPR Argument in a Relational Interpretation of Quantum Mechanics
It is shown that in the Rovelli relational interpretation of quantum mechanics, in which the notion of absolute or observer independent state is rejected, the conclusion of the ordinary EPR argument
On the Problem of Hidden Variables in Quantum Mechanics
The demonstrations of von Neumann and others, that quantum mechanics does not permit a hidden variable interpretation, are reconsidered. It is shown that their essential axioms are unreasonable. It
An analysis of the Einstein-Podolsky-Rosen correlations in terms of events
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
Einstein, Podolsky, Rosen, and Shannon
The Einstein–Podolsky–Rosen paradox (1935) is reexamined in the light of Shannon’s information theory (1984). The EPR argument did not take into account that the observer’s information was localized,
Quantum Foundations in the Light of Quantum Information
This paper reports three almost trivial theorems that nevertheless appear to have significant import for quantum foundations studies. 1) A Gleason-like derivation of the quantum probability law, but
Non-Representationalist Theories of Knowledge and Quantum Mechanics
Quantum Mechanics has imposed strain on traditional (dualist and representationalist) epistemological conceptions. An alternative was offered by Bohr and Heisenberg, according to whom natural science

All information in quantum systems is, notwithstanding Bell's theorem, localized. Measuring or otherwise interacting with a quantum system S has no effect on distant systems from which S is
The Significance of Information in Quantum Theory
A system of information-theoretic axioms is proposed from which the quantum formalism of quantum theory is derived and the twofold role of observer as physical system and as informational agent is analyzed.
