Delaying Quantum Choice Photons can display wavelike or particle-like behavior, depending on the experimental technique used to measure them. Understanding this duality lies at the heart of quantum mechanics. In two reports, Peruzzo et al. (p. 634) and Kaiser et al. (p. 637; see the Perspective on both papers by Lloyd) perform an entangled version of John Wheeler's delayed-choice gedanken experiment, in which the choice of detection can be changed after a photon passes through a double-slit to… 

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

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

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

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

Realization of an entanglement-assisted quantum delayed-choice experiment

The puzzling properties of quantum mechanics, wave-particle duality, entanglement and superposition, were dissected experimentally at past decades. However, hidden-variable (HV) models, based on

Experimental entanglement-assisted quantum delayed-choice experiment

The puzzling properties of quantum mechanics, wave-particle duality, entanglement and superposition, were dissected experimentally at past decades. However, hidden-variable (HV) models, based on

Simulation of quantum delayed-choice experiment through a single shot.

This work provides a simple and new route to inspect quantum duality, which does not require adjusting experimental parameters frequently and only needs performing measurement once.

A realizable delayed-choice quantum eraser, using a modified Mach-Zehnder (MZ) interferometer and polarization entangled photons, is theoretically analyzed here. The signal photon goes through a

Realistic interpretation of quantum mechanics and encounter-delayed-choice experiment

In this paper, a realistic interpretation (REIN) of the wave function in quantum mechanics is briefly presented. We demonstrate that in the REIN, the wave function of a microscopic object is its real

Experimental realization of a delayed-choice quantum walk.

This is the first experiment realizing a multi-dimensional quantum walk with a single photon source and the first experimental simulation of the Grover walk, a model that can be used to implement theGrover quantum search algorithm.

Experimental analysis of the quantum complementarity principle

One of the milestones of quantum mechanics is Bohr's complementarity principle. It states that a single quantum can exhibit a particle-like \emph{or} a wave-like behaviour, but never both at the same

Proposal for a quantum delayed-choice experiment.

This work proposes a framework to analyze quantum-controlled experiments and illustrates it by discussing a quantum version of Wheeler's delayed-choice experiment, showing that a photon can have a morphing behavior between particle and wave.

Experimental Evidence for a Photon Anticorrelation Effect on a Beam Splitter: A New Light on Single-Photon Interferences

We report on two experiments using an atomic cascade as a light source, and a triggered detection scheme for the second photon of the cascade. The first experiment shows a strong anticorrelation

This work reports an almost ideal realization of Wheeler's delayed-choice gedanken experiment with single photons allowing unambiguous which-way measurements.

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.

Delayed-choice test of quantum complementarity with interfering single photons.

An experimental test of quantum complementarity with single-photon pulses sent into a Mach-Zehnder interferometer with an output beam splitter of adjustable reflection coefficient R finds measured values of V and D to fulfill the complementarity relation V2+D2 < or =1.

Complementarity in the double-slit experiment: Quantum nonseparability and a quantitative statement of Bohr's principle

A detailed analysis of Einstein's version of the double-slit experiment, in which one tries to observe both wave and particle properties of light, is performed. Quantum nonseparability appears in the

Bohr's principle of complementarity (BPC) is the cornerstone of quantum mechanics. According to this principle, the total wavelike and particlelike information of a particle is limited by the
