To illustrate the quantum mechanical principle of complementarity, Bohr described an interferometer with a microscopic slit that records the particle's path. Recoil of the quantum slit causes it to become entangled with the particle, resulting in a kind of Einstein–Podolsky–Rosen pair. As the motion of the slit can be observed, the ambiguity of the particle's trajectory is lifted, suppressing interference effects. In contrast, the state of a sufficiently massive slit does not depend on the… 

Elementary analysis of interferometers for wave-particle duality test and the prospect of going beyond the complementarity principle

A distinct method to show a quantum object behaving both as wave and as particle is proposed and described in some detail. We make a systematic analysis using the elementary methodology of quantum

Atom interferometers with weak-measurement path detectors and their quantum mechanical analysis

According to the orthodox interpretation of quantum physics, wave-particle duality (WPD) is the intrinsic property of all massive microscopic particles. All gedanken or realistic experiments based on

Bohr’s Legacy in Cavity QED

Bohr played a central role in the interpretation of quantum mechanics. He based many discussions of its strange consequences on thought experiments. He imagined moving slit interferometers, able to

Observations of Deterministic Quantum Correlation Using Coherent Light

Complementarity theory is the essence of the Copenhagen interpretation in quantum mechanics. Since the Hanbury Brown and Twiss experiments, the particle nature of photons has been intensively

Proposal for a quantum delayed-choice experiment with a spin-mechanical setup

We describe an experimentally feasible protocol for performing a variant of the quantum delayed-choice experiment with massive objects. In this scheme, a single nitrogen-vacancy (NV) center in

Observations of near-perfect nonclassical correlation using coherent light

Complementarity theory is the essence of the Copenhagen interpretation. Since the Hanbury Brown and Twiss experiments, the particle nature of photons has been intensively studied for various quantum

Quantum Delayed-Choice Experiment with a Beam Splitter in a Quantum Superposition.

TLDR
A superconducting quantum circuit is configured as a Ramsey interferometer, where the element that acts as the first beam splitter can be put in a quantum superposition of its active and inactive states, as verified by the negative values of its Wigner function.

Observing wave/particle duality of light using topological charge

Wave particle duality, also called complementarity, is deeply rooted in the heart of quantum theory. It is fully exemplified in the famous Wheeler's delayed choice experiment where the choice of the

Classical wisdom of wave-particle duality says that it is impossible to observe simultaneously the wave and particle nature of microscopic object. Mathematically the principle requests that the

Origin of quantum-mechanical complementarity probed by a ‘which-way’ experiment in an atom interferometer

The principle of complementarity refers to the ability of quantum-mechanical entities to behave as particles or waves under different experimental conditions. For example, in the famous double-slit

Dephasing in electron interference by a ‘which-path’ detector

Wave–particle duality, as manifest in the two-slit experiment, provides perhaps the most vivid illustration of Bohr's complementarity principle: wave-like behaviour (interference) occurs only when

Manipulation of optical fields by atomic interferometry: Quantum variations on a theme by young

We analyze the principle of a very general and conceptually simple method for manipulating optical fields by coupling them into a matter waves Young double slit apparatus. The field, non resonant

Photon scattering from atoms in an atom interferometer: Coherence lost and regained.

TLDR
Experiments are discussed here in which this entanglement results from the elastic scattering of a photon from an atom initially in a state with extended spatial coherence inside an atom interferometer.

Observation of a "quantum eraser": A revival of coherence in a two-photon interference experiment.

TLDR
Experimental results are presented showing how the degree of erasure depends on the relative orientation of the polarizers, along with theoretical curves, and how the act of ``pasting together'' two previously distinguishable paths can introduce a new relative phase between them.

TLDR
The "welcher Weg" (which-path) detector employs a pair of initially empty micromaser cavities placed in front of a double-slit apparatus in an atomic interferometer and Velocity selection is shown to affect the visibility of the fringes.

Neutron interferometric double-resonance experiment.

TLDR
It is shown that under the given circumstances of neutron self-interference coherence is preserved in spite of the energy transfer to every neutron, which may stimulate renewed epistemological discussions about the interpretation of quantum mechanics.

Seeing a single photon without destroying it

Light detection is usually a destructive process, in that detectors annihilate photons and convert them into electrical signals, making it impossible to see a single photon twice. But this limitation

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

NONLOCAL MOMENTUM TRANSFER IN WELCHER WEG MEASUREMENTS

A “which-path” (welcher Weg) measurement necessarily destroys the fringes in a double-slit interference experiment. We show that in all instances one may attribute this destruction to a disturbance
