Motivated by some recent news, a journalist asks a group of physicists: "What's the meaning of the violation of Bell's inequality?" One physicist answers: "It means that non-locality is an established fact". Another says: "There is no non-locality; the message is that measurement outcomes are irreducibly random". A third one says: "It cannot be answered simply on purely physical grounds, the answer requires an act of metaphysical judgement". Puzzled by the answers, the journalist keeps asking…

Measuring Quantum Superpositions (Or, “It is only the theory which decides what can be observed.”)

In contraposition, following Einstein's claim according to which “it is only the theory which decides what can be observed”, this work proposes a return to the realist representational understanding of ‘physical theories’ in which ‘observation’ is considered as derived from theoretical presuppositions.

The operational reality of the quantum state and of its reduction

It is argued that it is possible, surprisingly, to address ontological questions concerning quantum mechanics on the basis of only operational considerations, and it is shown that the operational perspective itself provides an intrinsic interpretation of QM.

Understanding sequential measurements in psi-epistemic ontological models

It is shown that consideration of sequential measurements, and the fact that the quantum state changes during measurements, has been a neglected topic in this area as it places nontrivial restrictions on the structure of ψ-epistemic ontological models.

Ψ-epistemic Interpretations of Quantum Theory Have a Measurement Problem

It is demonstrated that all known epistemic ontological models of quantum theory in dimension $d\geq3, including those designed to evade the conclusion of the PBR theorem, cannot represent state update correctly.

Emergence of Time in a Participatory Universe

A new approach to interpret time is proposed and it is argued how it would emerge from the non-commutativity of quantum theory, assuming participatory realism.

Understanding Quantum Mechanics (Beyond Metaphysical Dogmatism and Naive Empiricism)

Quantum Mechanics (QM) has faced deep controversies and debates since its origin when Werner Heisenberg proposed the first mathematical formalism capable to operationally account for what had been

Quantum theory as a principle theory: insights from an information-theoretic reconstruction

We give a condensed and accessible summary of a recent derivation of quantum theory from information-theoretic principles, and use it to study the consequences of this and other reconstructions for

Quantum Locality, Rings a Bell?: Bell’s Inequality Meets Local Reality and True Determinism

By assuming a deterministic evolution of quantum systems and taking realism into account, we carefully build a hidden variable theory for Quantum Mechanics (QM) based on the notion of ontological

The Dilemma of Quantum Individuality Beyond Particle Metaphysics

It is commonly claimed that quantum mechanics makes reference to a microscopic realm constituted by elementary particles. However, as first famously noticed by Erwin Schrodinger, it is not at all

Evidence for the epistemic view of quantum states: A toy theory

We present a toy theory that is based on a simple principle: the number of questions about the physical state of a system that are answered must always be equal to the number that are unanswered in a

Einstein, Incompleteness, and the Epistemic View of Quantum States

It is shown that for models wherein the quantum state has the status of something real, the failure of locality can be established through an argument considerably more straightforward than Bell’s theorem.

The Many-worlds interpretation of quantum mechanics

This volume contains Dr. Everett's short paper from 1957, "'Relative State' Formulation of Quantum Mechanics," and a far longer exposition of his interpretation, entitled "The Theory of the Universal Wave Function," never before published.

Quantum-Bayesian Coherence

It is argued that the Born Rule should be seen as an empirical addition to Bayesian reasoning itself, and how to view it as a normative rule in addition to usual Dutch-book coherence is shown.

"Relative State" Formulation of Quantum Mechanics

The task of quantizing general relativity raises serious questions about the meaning of the present formulation and interpretation of quantum mechanics when applied to so fundamental a structure as

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

A SUGGESTED INTERPRETATION OF THE QUANTUM THEORY IN TERMS OF "HIDDEN" VARIABLES. II

In this paper, we shall show how the theory of measurements is to be understood from the point of view of a physical interpretation of the quantum theory in terms of hidden variables developed in a

Quantum theory makes the most accurate empirical predictions and yet it lacks simple, comprehensible physical principles from which the theory can be uniquely derived. A broad class of probabilistic

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
