Comment on "On Phase Selective Quantum Eraser" (arXiv:1501.00817 [quant-ph])

Abstract

In a recent interesting article A. Heuer, G. Pieplow, and R. Menzel discuss a quantum-eraser experiment to investigate the complementarity of wave-like and particle-like behavior of photons. I would like to draw your attention to the fact that the very same experimental setup was suggested in a previous paper, and take advantage of this opportunity to examine some aspects of this controversial subject.

Comment on Wave-particle duality revisited: Neither wave nor particle

Luiz Carlos Ryff

In a recent article Jan Sperling, Syamsundar De, Thomas Nitsche, Johannes Tiedau, Sonja Barkhofen, Benjamin Brecht, and Christine Silberhorn discuss the wave-particle duality using an experiment to demonstrate that "neither the wave nor the particle description is sufficient to predict the utcomes of quantum-optical experiments." I would like to draw your attention to two previous papers that discuss feasible experiments in which a photon does not seem to behave either as particle or as wave and make some brief considerations on the topic.

The Quantum Eraser Does Not Always Erase

António Cardoso, João L. Cordovil, J. R. Croca

In this paper we will first look at a particular quantum eraser setup to show that this type of experiments can be understood in an intuitive manner if we are willing to take a complex nonlinear approach, without the need to invoke Niels Bohr's complementarity or quantum entanglement between two particles. We will then discuss a recent experiment of the same type that does not erase the interference pattern when which-path information is available, and argue that this result is in clear contradiction with the orthodox interpretation of quantum mechanics but perfectly understandable in the framework of nonlinear quantum physics.

Phase-selective quantum eraser

Axel Heuer, Gregor Pieplow, R. Menzel

A quantum-eraser experiment with photon pairs coupled via induced coherence is reported, and the complementarity between which-source information and two-photon-interference-fringe visibility is demonstrated.

Complementarity quantified and quantum erasers revisited

Peter D. D. Schwindt, Paul G. Kwiat, Andrew G. White

Summary form only given.The principle of complementarity, which describes the wave-particle duality of quanta, is one of the cornerstones of modern quantum theory. However, only recently has it been described quantitatively. Experimental verifications have been even rarer. Here we describe an experiment in which the quantified principle of complementarity is demonstrated for a variety of input quantum states, including mixed states.

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

Aurélien Drezet

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.

Comment on "Relativity of Quantum States in Entanglement Swapping: Violation of Bell's Inequality with no Entanglement"

Luiz Carlos Ryff

In a recent interesting article Chris Nagele, Ebubechukwu O. IloOkeke, Peter P. Rohde, Jonathan P. Dowling, and Tim Byrnes discuss an entanglement swapping experiment using a setup where it is possible to switch the time ordering of measurements. I would like to draw your attention to the fact that the very same idea was introduced in two previous papers, and briefly address some important points related to the subject.
