Facts happen at every interaction, but they are not absolute: they are relative to the systems involved in the interaction. Stable facts are those whose relativity can effectively be ignored. In this work, we describe how stable facts emerge in a world of relative facts and discuss their respective roles in connecting quantum theory and the world. The distinction between relative and stable facts resolves the difficulties pointed out by the no-go theorem of Frauchiger and Renner, and is… 
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
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
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
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.

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
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
Law of Total Probability in Quantum Theory and Its Application in Wigner’s Friend Scenario
It is well-known that the law of total probability does not generally hold in quantum theory. However, recent arguments on some of the fundamental assumptions in quantum theory based on the extended
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
Collective patterns and stable misunderstandings in networks striving for consensus without a common value system
TLDR
This work introduces a model of interacting agents that strive for consensus, however, each with only a subjective perception of the world and a communication model that does not presuppose a definition of right or wrong and the actors can hence not distinguish between correct and incorrect observations.

Quantum theory cannot consistently describe the use of itself
TLDR
A variant of Wigner’s friend Gedankenexperiment where each of the current interpretations of QM fails in giving a consistent description, indicating that quantum theory cannot be extrapolated to complex systems, at least not in a straightforward manner.

Implications of Local Friendliness Violation for Quantum Causality
TLDR
It is suggested that cleaving to Leibniz’s principle requires extending relativity to events themselves, and this formulation of the Local Friendliness no-go theorem of Bong et al. is provided.
Respecting One’s Fellow: QBism’s Analysis of Wigner’s Friend
According to QBism, quantum states, unitary evolutions, and measurement operators are all understood as personal judgments of the agent using the formalism. Meanwhile, quantum measurement outcomes
A strong no-go theorem on the Wigner’s friend paradox
Does quantum theory apply at all scales, including that of observers? New light on this fundamental question has recently been shed through a resurgence of interest in the long-standing Wigner’s
Even performed pre-measurements have no results
The title of our work is a paraphrase of the title of Asher Peres' paper \textit{Unperformed experiments have no results}. We show what are the lessons to be learned from the gedankenexperiments
Completing the quantum formalism: why and how ?
In standard quantum mechanics (QM), a state vector $| \psi \rangle$ may belong to infinitely many different orthogonal bases, as soon as the dimension $N$ of the Hilbert space is at least three. On
Decoherence framework for Wigner's-friend experiments
TLDR
This framework shows that the agents' claims become consistent if the changes in their memories are properly taken into account, and can be used to build a consistent scenario for the recently proposed extended versions of the Wigner's-friend experiment.
A Generic Model for Quantum Measurements
TLDR
A unified picture of quantum measurements within this approach is provided, and the role of the system–context dichotomy, and of quantum interferences are justified, and links with stochastic quantum thermodynamics, and with algebraic quantum theory are discussed.
Testing the reality of Wigner's friend's experience
TLDR
In this thought experiment, an observer is considered (Wigner’s friend) who is able to per- form measurement on the quantum system and assign a quantum state that does not ascribe a well-defined value to the outcome of the friend’'s observation, in apparent contradiction with the friend's perspective.
