Abstract A recent experiment performed by S. Afshar [first reported by M. Chown, New Sci. 183:30, 2004] is analyzed. It was claimed that this experiment could be interpreted as a demonstration of a violation of the principle of complementarity in quantum mechanics. Instead, it is shown here that it can be understood in terms of classical wave optics and the standard interpretation of quantum mechanics. Its performance is quantified and it is concluded that the experiment is suboptimal in the… 
Complementarity Paradox Solved: Surprising Consequences
Afshar et al. claim that their experiment shows a violation of the complementarity inequality. In this work, we study their claim using a modified Mach-Zehnder setup that represents a simpler version
Limitations imposed by complementarity
For two-level systems, it is shown that any preparation violating complementarity enables the preparation of a non-signalling box violating Tsirelson’s bound, which could be used to distinguish a plethora of non-orthogonal quantum states and hence enable improved cloning protocols.
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
Quantum Histories and Quantum Complementarity
The origin of quantum complementarity is discussed using Feynman's sum-over-histories approach to Quantum Mechanics and an explanation why Englert-Greenberger duality relation cannot be violated experimentally if the standard QM postulates are accepted.
Wave Particle Duality and the Afshar Experiment
In an interesting series of articles published few years ago Afshar and coworkers [1,2] reported an optical experiment in which they claimed to refute the well known N. Bohr principle of
Illustration of quantum complementarity using single photons interfering on a grating
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
Complementarity controversy in wave-particle duality revisited
On the face of some recent experiments claiming the simultaneous presence of both ‘sharp interference’ and ‘highly reliable which way information’ and some others casting light on the origin of
Quantum Particle Di ff raction by a Classical Method
Numerical simulations of the double slit experiment with el ectrons, done by Al Rabeh, are repeated and improved. As well, the simulations go from m oved Coulomb charges. These tests are extended
A Bohmian Analysis Of Afshar's Experiment
This work is about Bohmian mechanics, a non-relativistic quantum theory about the motion of particles and their trajectories, named after its inventor David Bohm (Bohm,1952). This mechanics resolves


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
Paradox in Wave-Particle Duality
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
Path detection and the uncertainty principle
QUANTUM mechanics predicts that any detector capable of determining the path taken by a particle through a double slit will destroy the interference. This follows from the principle of

We describe a new version of the well-known gedanken experiments to determine which of the two paths a particle took in a two-beam interference experiment. In this version the presence of a geometric

A unified treatment of a number of double-slit experiments which give «which-path» information shows that the loss of coherence may always be described in terms of a stochastic disturbance to the system due to coupling with the path detector.
Generalized absorber theory and the Einstein-Podolsky-Rosen paradox
A generalized form of Wheeler-Feynman absorber theory is used to explain the quantum-mechanical paradox proposed by Einstein, Podolsky, and Rosen (EPR). The advanced solutions of the electromagnetic
Quantum optical tests of complementarity
Simultaneous observation of wave and particle behaviour is prohibited, usually by the position–momentum uncertainty relation. New detectors, constructed with the aid of modern quantum optics, provide
Quantum statistics can suppress classical interference
Classical optical interference experiments correspond to a measurement of the first-order correlation function of the electromagnetic field. The converse of this statement: experiments that measure

An inequality is derived according to which the fringe visibility in a two-way interferometer sets an absolute upper bound on the amount of which-way information that is potentially stored in a

The forty-nine papers collected here illuminate the meaning of quantum theory as it is disclosed in the measurement process. Together with an introduction and a supplemental annotated bibliography,
