Reply to arXiv:2111.13357 ("The Quantum Eraser Non-Paradox'')

TL;DR

This paper responds to a critique of a previous work by clarifying that certain superpositions of detector states are not relevant to their models and have not been observed in experiments.

Contribution

The authors clarify that their models do not involve superpositions of detector eigenstates, countering the criticism and emphasizing the empirical non-observation of such superpositions.

Findings

Superpositions of detector eigenstates are not present in the models.

No experimental evidence for detector superpositions has been observed.

The critique's concern does not apply to the models discussed.

Abstract

In a recent criticism (arXiv:2111.13357) of our paper arXiv:2111.09347, Drezet argues that we have forgotten to consider superpositions of detector eigenstates. However, such superpositions do not occur in the models our paper is concerned with. We also note that no one has ever observed such detector superpositions.
