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

TL;DR

This paper critiques a previous study on quantum wave function measurement, identifying a normalization error that undermines the original proposal's validity.

Contribution

It highlights a crucial normalization mistake in the prior work, challenging its conclusions about measurement techniques.

Findings

Normalization error invalidates the original proposal

Reassessment of measurement accuracy in quantum wave function

Implications for future quantum measurement methods

Abstract

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.
