Wave-particle duality is strikingly illustrated by Wheeler's delayed-choice gedanken experiment, where the configuration of a two-path interferometer is chosen after a single-photon pulse has entered it: Either the interferometer is closed (that is, the two paths are recombined) and the interference is observed, or the interferometer remains open and the path followed by the photon is measured. We report an almost ideal realization of that gedanken experiment with single photons allowing… 

Wheeler's delayed-choice thought experiment: Experimental realization and theoretical analysis

Wheeler has strikingly illustrated the wave-particle duality by the delayed-choice thought experiment, in which the configuration of a 2-path interferometer is chosen after a single-photon

Wheeler’s delayed-choice experiment based on Rydberg atoms

The delayed choice gedanken-experiment initially proposed by J A Wheeler reveals the nontrivial features of wave–particle duality in quantum world, that is, the choice of whether to observe the

Delayed-choice gedanken experiments and their realizations

The wave-particle duality dates back to Einstein's explanation of the photoelectric effect through quanta of light and de Broglie's hypothesis of matter waves. Quantum mechanics uses an abstract

Experimental realization of causality-assisted Wheeler's delayed-choice experiment using single photons

Wave-particle duality is one of the most intriguing features in quantum physics. A well-known gedanken experiment that provides evidence for this is the Wheeler's delayed-choice experiment based on a

Extending Wheeler’s delayed-choice experiment to space

This work exploits temporal and polarization degrees of freedom of photons reflected by a fast-moving satellite equipped with retroreflecting mirrors to exploit the dual wave-particle duality of light at the unprecedented distance of low-Earth-orbit satellites.

Quantum Delayed-Choice Experiment and Wave-Particle Superposition

We propose a simple implementation scheme of quantum delayed-choice experiment in linear optical system without initial entanglement resource. By choosing different detecting devices, one can

Quantum wave–particle superposition in a delayed-choice experiment

Wave-particle duality epitomizes the counterintuitive character of quantum physics. A striking illustration is the quantum delay-choice experiment, which is based on Wheeler's classic delayed-choice

Corpuscular event-by-event simulation of quantum optics experiments: application to a quantum-controlled delayed-choice experiment

A corpuscular simulation model of optical phenomena that does not require knowledge of the solution of a wave equation of the whole system and reproduces the results of Maxwell's theory by generating

Realization of quantum Wheeler's delayed-choice experiment

Light is believed to exhibit wave–particle duality1 depending on the detecting devices, according to Bohr's complementarity principle2, as has been demonstrated by the ‘delayed-choice experiment’

Optical proposals for controlled delayed-choice experiment based on weak cross-Kerr nonlinearities

Two theoretical proposals to exhibit the wave–particle duality of the photon with the assistance of weak cross-Kerr nonlinearities are proposed.

Delayed "Choice" quantum eraser

The experimental results demonstrate the possibility of delayed determination of particlelike or wavelike behavior via quantum entanglement, and the which-path or both-path information of a quantum can be marked or erased by its entangled twin even after the registration of the quantum.
