We examine the entanglement and state disturbance arising in a protective measurement and argue that these inescapable effects doom the claim that protective measurement establishes the reality of the wave function. An additional challenge to this claim results from the exponential number of protective measurements required to reconstruct multi-qubit states. We suggest that the failure of protective measurement to settle the question of the meaning of the wave function is entirely expected, for…

The ontological status of the wave function in quantum mechanics is usually analyzed in the context of conventional impulsive measurements. These analyses are always based on some nontrivial
Why protective measurement does not establish the reality of the quantum state
TLDR
Three counter-arguments are provided to construct explicit “psi $$ψ-epistemic” toy models for protective measurement, which strongly suggest that protective measurement does not imply the reality of the quantum state.
A PBR-like argument for psi-ontology in terms of protective measurements
The ontological status of the wave function in quantum mechanics has been analyzed in the context of conventional projective measurements. These analyses are usually based on some nontrivial
The Meaning of the Wave Function: In Search of the Ontology of Quantum Mechanics
The meaning of the wave function has been a hot topic of debate since the early days of quantum mechanics. Recent years have witnessed a growing interest in this long-standing question. Is the wave
Why protective measurement establishes the reality of the wave function
It has been debated whether protective measurement implies the reality of the wave function. In this paper, I present a new analysis of the relationship between protective measurement and the reality
On the reality and meaning of the wave function
In this article, we give a clearer argument for the reality of the wave function in terms of protective measurements, which does not depend on nontrivial assumptions and also overcomes existing

TLDR
This essay explores how such a claim that John von Neumann was the ‘first quantum Bayesian’ is, historically speaking, unsupported.
