Contemporary non-representationalist interpretations of the quantum state (especially QBism, neo-Copenhagen views, and the relational interpretation) maintain that quantum states codify observer-relative information. This paper provides an extensive defense of such views, while emphasizing the advantages of, specifically, the relational interpretation. The argument proceeds in three steps: (1) I present a classical example (which exemplifies the spirit of the relational interpretation) to… 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 interpretationsExpand
Understanding quantum mechanics: a review and synthesis in precise language
TLDR
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. Expand
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 outcomesExpand
Entropy in Foundations of Quantum Physics
TLDR
Entropy can be used in studies on foundations of quantum physics in many different ways, each of them using different properties of this mathematical object to study the properties of the object itself. 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 aExpand
Quantum erasing the memory of Wigner's friend
TLDR
It is argued that the three apparently incompatible properties used to question the consistency of quantum mechanics correspond to two logically distinct contexts: either assuming that Wigner has full control over his friends' lab, or conversely that some part of the labs remain unaffected byWigner's subsequent measurements.

TLDR
It is argued that quantum mechanics should be understood probabilistically, as a new sort of non-Boolean probability theory, rather than representationally, as an theory about the elementary constituents of the physical world and how these elements evolve dynamically over time. Expand
