Causality, memory erasing, and delayed-choice experiments

Yakir Aharonov, Sandu Popescu, Lev Vaidman A

Abstract

A recent proposal of a ``quantum eraser'' by Ingraham [Phys. Rev. A 50, 4502 (1994); 51, 4295(E) (1995)] is analyzed. It is shown that Ingraham's predictions contradict relativistic causality and, therefore, cannot be right. A subtle quantum effect that was overlooked by Ingraham is explained.

The Delayed Quantum Eraser Experiment Explained Classically

Declan Traill

This paper discusses the well-known delayed choice Quantum Eraser experiment performed by Kim et al. in 2000 and analyzes it from a Classical Physics perspective. I have included a diagram of the setup used in the experiment. I show that the result of the experiment can be explained by Classical Physics and does not require “Spooky action at a distance” due to entangled particles, as Einstein famously once put it, nor events modifying the past due to the delayed choice aspect of the experiment.

Delayed Choice Quantum Eraser Experiment Revisited: Causality and Informational Coherence

Taku Ohwada

An operationally well-defined delayed-choice quantum-eraser experiment is proposed, realizing a genuine delayed choice within presently available quantum-optical technology. A multimode quantum memory supplies a controlled and verifiable delay, ensuring that the choice operation is applied strictly after the observation event. Electronic single-photon interference detection measurements furnish a direct statistical discriminator between the causal and informational coherence hypotheses, based solely on marginal detection statistics and without any post-selection.

A Classical Explanation for the Delayed Quantum Eraser Experiment

Declan Traill

This work examines the well-known delayed choice Quantum Eraser experiment carried out by Kim et al in 2000 from the standpoint of Classical Physics. I've drawn a diagram of the experiment's setup. I show that the experiment's outcome can be explained using Classical Physics, and that it does not require "spooky action at a distance" owing to entangled particles, as Einstein famously put it, nor events changing the past due to the experiment's delayed choice feature.

Stage analysis of delayed-choice and quantum eraser experiments

George Jaroszkiewicz

Delayed choice and quantum eraser experiments have attracted much interest recently, both theoretically and experimentally. In particular, they have prompted suggestions that quantum mechanics involves acausal effects. Using a recently developed approach which takes apparatus into account, we present a detailed analysis of various double-slit experiments to show that this is never the case. Instead, quantum experiments can be described in terms of a novel concept of time called stages. These can cut across the conventional linear time parameter as experienced in the laboratory and appear to violate causality.

Quantum eraser: A proposed photon correlation experiment concerning observation and "delayed choice" in quantum mechanics

Marlan O. Scully, Kai J. Drühl

We propose and analyze an experiment designed to probe the extent to which information accessible to an observer and the "eraser" of this information affects measured results. The proposed experiment could also be operated in a "delayed-choice" mode.
