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
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.
Information is Physical: Cross-Perspective Links in Relational Quantum Mechanics
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.
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
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
Barad, Bohr, and quantum mechanics
The last decade has seen an increasing number of references to quantum mechanics in the humanities and social sciences. This development has in particular been driven by Karen Barad’s agential
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
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


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 belongs to quantum theory is no more than what is needed for its derivation. Keeping to this maxim, we record a paradigmatic shift in the foundations of quantum mechanics, where the focus has
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
The Impossibility of Accurate State Self-Measurements
It is shown that it is impossible for an observer to distinguish all present states of a system in which he or she is contained, irrespective of whether this system is a classical or a quantum
“Incerto Tempore, Incertisque Loci”: Can We Compute the Exact Time at Which a Quantum Measurement Happens?
Without addressing the measurement problem (i. e., what causes the wave function to “collapse,” or to ”branch,” or a history to become realized, or a property to actualize), I discuss the problem of
Is There a Fundamental Level
1. Talk about ‘‘the fundamental level of reality’’ pervades contemporary metaphysics. The fundamentalist starts with (a) a hierarchical picture of nature as stratified into levels, adds (b) an
Conceptual Progress and Word/World Relations: In Search of the Essence of Natural Kinds
The problem of natural kinds forms the busy crossroads where a number of larger problems meet: the problem of universals, the problem of induction and projectibility, the problem of natural laws and
Information-Theoretic Princple Entails Orthomodularity of a Lattice
No HeadingQuantum logical axiomatic systems for quantum theory usually include a postulate that a lattice under consideration is orthomodular. We propose a derivation of orthomodularity from an
This work analyzes the axioms underlying a few information-theoretic derivations of the formalism of quantum theory and proposes a conceptual framework in which, by combining several approaches, one can retrieve more of the conventional quantum formalism.
