A recent experiment performed by Afshar et al (2007 Found. Phys. 37 295-305) has been interpreted as a violation of Bohr's complementarity principle between interference visibility and which-path information (WPI) in a two-path interferometer. We have reproduced this experiment, using true single- photon pulses propagating in a two-path wavefront-splitting interferometer realized with a Fresnel's biprism, and followed by a grating with adjustable transmitting slits. The measured values of…

Towards simultaneous observation of path and interference of a single photon in a modified Mach–Zehnder interferometer
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
Spying on photons with photons: quantum interference and information
Abstract The quest to have both which-path knowledge and interference fringes in a double-slit experiment dates back to the inception of quantum mechanics (QM) and to the famous Einstein-Bohr

Bohr's principle of complementarity states that every quantum system has mutually incompatible properties which cannot be simultaneously measured [1]. This principle is commonly illustrated by
Complementarity, quantum erasure and delayed choice with modified Mach-Zehnder interferometers
Abstract Often cited dictums in Quantum Mechanics include “observation disturbance causes loss of interference” and “ignorance is interference”. In this paper we propose and describe a series of
Testing foundations of quantum mechanics with photons
Quantum mechanics continues to predict effects at odds with a classical understanding of nature. Experiments with light at the single-photon level have historically been at the forefront of
Weak-measurement Mach-Zehnder interferometer for testing wave-particle duality
The Mach-Zehnder interferometer (MZI) is a regular yet simple instrument to test wave-particle duality. One key device in a standard MZI is the beam splitter 2 (BS2). Here we make a simple quantum
Modified Two-Slit Experiments and Complementarity
Some modified two-slit interference experiments claim to demonstrate a violation of Bohr’s complementarity principle. A typical such experiment is theoretically analyzed using wave-packet dynamics.
Revisiting Bohr's principle of complementarity with a quantum device
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

Delayed-choice test of quantum complementarity with interfering single photons.
TLDR
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.
Single-photon wavefront-splitting interference
Abstract.We present a new realization of the textbook experiment consisting in single-photon interference based on the pulsed, optically excited photoluminescence of a single colour centre in a
A complementarity experiment with an interferometer at the quantum–classical boundary
TLDR
An experimental investigation of complementarity using an interferometer in which the properties of one of the beam-splitting elements can be tuned continuously from being effectively microscopic to macroscopic, illustrating the quantum to classical transition.
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
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

We report on the simultaneous determination of complementary wave and particle aspects of light in a double-slit type “welcher-weg” experiment beyond the limitations set by Bohr’s Principle of

We have experimentally demonstrated the interferometric complementarity, which relates the distinguishability D quantifying the amount of which-way (WW) information to the fringe visibility V
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.
