Reply to Comments of Steuernagel on the Afshar's Experiment

TL;DR

This paper defends the authors' interpretation of the Afshar experiment against Steuernagel's criticism, emphasizing the importance of consistent experimental conditions in analyzing wave-particle complementarity.

Contribution

It clarifies the correct method to evaluate fringe visibility in the Afshar experiment, countering previous derivations that used inconsistent experimental setups.

Findings

Steuernagel's derivation is incorrect due to inconsistent experimental conditions.

Proper analysis supports the authors' original interpretation of the Afshar experiment.

Highlights the importance of consistent experimental configurations in quantum complementarity studies.

Abstract

We respond to criticism of our paper "Paradox in Wave-Paricle Duality for Non-Perturbative Measurements". We disagree with Steuernagel's derivation of the visibility of the Afshar experiment. To calculate the fringe visibility, Steuernagel utilizes two different experimental situations, i.e. the wire grid in the pattern minima and in the pattern maxima. In our assessment, this proceduere cannot lead to the correct result for the complementarity properties of wave-particle in one particular experimental set-up.
