Comment on "How to protect the interpretation of the wave function against protective measurements" by Jos Uffink

Abstract

It is shown that Uffink's attempt to protect the interpretation of the wave function against protective measurements fails due to several errors in his arguments.

Reply to Gao’s ”Comment on ”How to protect the interpretation of the wave function against protective measurements”

Jos Uffink

Shan Gao (Gao 2011) recently presented a critical reconsideration of a paper I wote (Uffink 1999) on the subject of protective measurement. Here, I take the occasion to reply to his objections.

Comment on "Strong Measurements Give a Better Direct Measurement of the Quantum Wave Function"

Varad R. Pande, Som Kanjilal, Debmalya Das

This is a comment on "Strong Measurements Give a Better Direct Measurement of the Quantum Wave Function" which was published as PRL 116, 040502 (2016). We show that there is crucial normalization error in this Letter which invalidates the proposal.

How to protect the interpretation of the wave function against protective measurements

Jos Uffink

A new type of procedures, called protective measurements, was proposed by Aharonov, Anandan, and Vaidman [Phys. Rev. A 97, 4616 (1993); Found. Phys. 26, 117 (1996)]. These authors argued that a protective measurement allows the determination of arbitrary observables of a single quantum system, and claimed that this favors a realistic interpretation of the quantum state. This paper proves that only observables that commute with the system's Hamiltonian can be measured protectively. It is argued that this restriction saves the coherence of alternative interpretations.
