Comment on 'Operator formalism for the Wigner phase distribution'

TL;DR

This paper critiques the operator formalism for the Wigner phase distribution, highlighting that the operator linked to the radially integrated Wigner function is unjustified as a phase operator.

Contribution

It provides a critical analysis showing the operator for the Wigner phase distribution is not a valid phase operator.

Findings

The operator lacks proper justification as a phase operator.

The critique questions the validity of the operator formalism.

Highlights the need for alternative approaches to phase measurement.

Abstract

The operator associated with the radially integrated Wigner function is found to lack justification as a phase operator.
