The relational interpretation of quantum mechanics proposes to solve the measurement problem and reconcile completeness and locality of quantum mechanics by postulating relativity to the observer for events and facts, instead of an absolute “view from nowhere”. The aim of this paper is to clarify this interpretation, and in particular, one of its central claims concerning the possibility for an observer to have knowledge about other observer’s events. I consider three possible readings of this… 

Open Problems in Relational Quantum Mechanics

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 an interpretation of quantum theory based on the idea of abolishing the notion of absolute states of systems, in favor of states of systems relative to other

Does Science need Intersubjectivity? The Problem of Confirmation in Orthodox Interpretations of Quantum Mechanics

What must an interpretation of quantum mechanics do in order to be considered viable? We suggest that one vitally important criterion is the following: Any successful interpretation of quantum

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

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

What Ontology for Relational Quantum Mechanics?

In this paper, we evaluate some proposals that have been put forward to clarify the ontological consequences of relational quantum mechanics. We first focus on priority monism and ontic structural

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 World as a Quantum Information Processor

It is claimed that the world is fully quantum, and the classical world is but a limit case of the quantum world, and quantum information can be taken as a living phenomenon.

Understanding quantum mechanics: a review and synthesis in precise language

This review is broad in scope, and aims to reflect enough of the literature to be representative of the current state of the subject, and to contribute to achieving greater consensus on how to understand quantum mechanics.

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 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

What is quantum mechanics trying to tell us

I explore whether it is possible to make sense of the quantum mechanical description of physical reality by taking the proper subject of physics to be correlation and only correlation, and by

Relational Quantum Mechanics and the Determinacy Problem

Carlo Rovelli's relational interpretation of quantum mechanics leaves us with a paradox having to do with the determinacy of measurement outcomes, which can be accepted only if the authors are willing to give up on certain elements of the ‘absolute’ view of the world.

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

A Perspectival Version of the Modal Interpretation of Quantum Mechanics and the Origin of Macroscopic Behavior

We study the process of observation (measurement), within the framework of a “perspectival” (“relational,” “relative state”) version of the modal interpretation of quantum mechanics. We show that if
