On Relationalist Reconstructions of Quantum Theory

  title={On Relationalist Reconstructions of Quantum Theory},
  author={Blake C. Stacey},
One appealing feature of Carlo Rovelli’s proposal for “Relational Quantum Mechanics” [1] is that it offered a challenge for those who prefer technical work over slinging sentences: the reconstruction of quantum theory from information-theoretic principles. This appeal was witnessed by the means through which I first learned of RQM, a Wikipedia page written by a fan in 2006 [2] and since trimmed heavily on the grounds that it said many things not explicitly stated in the literature already. (As… 

Is Relational Quantum Mechanics about Facts? If So, Whose? A Reply to Di Biagio and Rovelli's Comment on Brukner and Pienaar

Relational Quantum Mechanics is an interpretation of quantum theory championed by Rovelli [1, 2]. Recently, Brukner and Pienaar separately wrote critiques of RQM [3–5], to which Di Biagio and Rovelli

Relational Quantum Mechanics is About Facts, Not States: A Reply to Pienaar and Brukner

In recent works, Časlav Brukner and Jacques Pienaar have raised interesting objections to the relational interpretation of quantum mechanics. We answer these objections in detail and show that, far

The De-Relationalizing of Relational Quantum Mechanics

A recent phase transition in the relational interpretation of quantum mechanics (RQM) is situated in its historical context, and the novelty of the post-transition viewpoint is questioned.



Some Negative Remarks on Operational Approaches to Quantum Theory

This talk hopes to expand on points and convey some sense of why the author is fascinated with the problem of the symmetric informationally complete POVMs to an extent greater than axiomatic reconstructions.

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 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

Comment on “The Notion of Locality in Relational Quantum Mechanics”

A recent paper [P. Martin-Dussaud, C. Rovelli, F. Zalamea, arXiv:1806.08150] has given a lucid treatment of Bell's notion of local causality within the framework of the relational interpretation of

QBism: Quantum Theory as a Hero's Handbook

This paper represents an elaboration of the lectures delivered by one of us (CAF) during "Course 197 -- Foundations of Quantum Physics" at the International School of Physics "Enrico Fermi" in

A general view of science, and not just of quantum mechanics, is applied to a long-standing puzzle in classical physics: the apparent inability of physics to give any meaning to 'Now'-the present moment.

Introducing the Qplex: a novel arena for quantum theory

Abstract We reconstruct quantum theory starting from the premise that, as Asher Peres remarked, “Unperformed experiments have no results.” The tools of quantum information theory, and in particular

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

Born's rule as a quantum extension of Bayesian coherence

The subjective Bayesian interpretation of probability asserts that the rules of the probability calculus follow from the normative principle of Dutch-book coherence: A decision-making agent should


THE paradox of Einstein, Podolsky and Rosen [1] was advanced as an argument that quantum mechanics could not be a complete theory but should be supplemented by additional variables. These additional
