# Is the Quantum State Real? An Extended Review of -ontology Theorems

@inproceedings{Leifer2014IsTQ, title={Is the Quantum State Real? An Extended Review of -ontology Theorems}, author={Matthew Leifer}, year={2014} }

Towards the end of 2011, Pusey, Barrett and Rudolph derived a theorem that aimed to show that the quantum state must be ontic (a state of reality) in a broad class of realist approaches to quantum theory. This result attracted a lot of attention and controversy. The aim of this review article is to review the background to the Pusey–Barrett–Rudolph Theorem, to provide a clear presentation of the theorem itself, and to review related work that has appeared since the publication of the Pusey…

Quantum states are the fundamental elements in quantum theory. However, there are a lot of discussions and debates about what a quantum state actually represents. Is it corresponding directly to…

The Pusey-Barrett-Rudolph (PBR) no-go theorem provides an argument for the reality of the quantum state by ruling out {\psi}-epistemic ontological theories, in which the quantum state is of a…

### The operational reality of the quantum state and of its reduction

- Physics
- 2020

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

- Philosophy
- 2019

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.

### The End of a Classical Ontology for Quantum Mechanics?

- PhilosophyEntropy
- 2021

It is argued that the Shrapnel–Costa no-go theorem undermines the last remaining viability of the view that the fundamental ontology of quantum mechanics is essentially classical, and that accepting causal symmetry is more economical than rejecting a classical ontology.

### Is a time symmetric interpretation of quantum theory possible without retrocausality?

- PhilosophyProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
- 2017

It is shown that the assumption that a time symmetric ontology for quantum theory must necessarily be retrocausal can be replaced by a different assumption, called λ-mediation, that plausibly holds independently of the status of the quantum state, and that this assumption implies a timelike analogue of Bell's local causality criterion.

### Einstein, Incompleteness, and the Epistemic View of Quantum States

- Philosophy
- 2007

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.

### Topics in Quantum Foundations: Ontological Models, and Distinguishability as a Resource

- Computer Science
- 2009

This thesis adds a new result which shows that measurements in a model where the quantum state represents information must be contextual, and refine the generalized notion of contextuality into strong and weak forms in order to parse the relationship between new and old results.

### ψ-Epistemic models are exponentially bad at explaining the distinguishability of quantum states.

- PhilosophyPhysical review letters
- 2014

This Letter exhibits a family of states for which the ratio of these two quantities must be ≤2de-cd in Hilbert spaces of dimension d that are divisible by 4, which implies that the epistemic explanation of indistinguishability becomes implausible at an exponential rate as the Hilbert space dimension increases.

### No ψ-epistemic model can fully explain the indistinguishability of quantum states.

- PhysicsPhysical review letters
- 2014

This work considers models that are defined for a single quantum system of dimension d, such that the independence condition does not arise, and derives an upper bound on the extent to which the probability distributions can overlap.

### No-go theorems for ψ-epistemic models based on a continuity assumption.

- PhilosophyPhysical review letters
- 2013

This argument is different from the recent proof of Pusey, Barrett, and Rudolph and it already yields a nontrivial constraint on ψ-epistemic models using a single copy of the system in question.
