The Quantum Eraser Non-Paradox: a comment on arXiv:2111.09347v1

TL;DR

This paper clarifies misconceptions about the quantum eraser experiment, arguing that the apparent paradox arises from prejudiced assumptions about retrocausality rather than the phenomenon itself.

Contribution

It provides a precise critique of previous interpretations, emphasizing that the paradox is due to prejudice rather than actual retrocausal effects.

Findings

The grand father-paradox is based on prejudice, not retrocausality.

Clarifies methodology of previous comments on quantum eraser.

Argues that the paradox does not imply non-locality or retrocausality.

Abstract

This is a short reply to arXiv:2112.00436v1 and arXiv:2111.09347v1 by C. Bracken, J.R. Hance, and S. Hossenfelder. I precise some elements concerning i) the methodology of my previous version of the comment [arXiv:2111.13357v3] to arXiv:2111.09347v1, and ii) why the grand father-paradox (causal loop) presented in their article comes from a prejudice concerning retrocausality not from retrocausality or locality themselves.
