Using an unbalanced SU(1,1) interferometer, we study the dependence of interference upon filter bandwidth. We find that under some conditions depending on entanglement, the coherence time does not change when optical filtering is applied.

Induced coherence and indistinguishability in optical interference.

The interpretation of second-order interference in the superposition of signal photons from two coherently pumped parametric down-converters is discussed in terms of the intrinsic indistinguishability of the photon paths.

Quantum state engineering by nonlinear quantum interference

The success of many protocols in optical quantum information processing relies on the availability of photon states with a well-defined spatial and temporal mode, but the latter is often difficult to

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

Turning off quantum duality

We provide the first experimental confirmation of a three-way quantum coherence identity possessed by single pure-state photons. Our experimental results demonstrate that traditional wave-particle

Coherence Constraints and the Last Hidden Optical Coherence.

A new domain of optical coherence is discovered, and it is shown that it is the third and last member of a previously unreported fundamental triad of coherences, unified by the derivation of a parallel triadic constraints that take the form of complementarity relations.

Quantum SU(1,1) interferometers: Basic principles and applications

A new type of quantum interferometer was recently realized that employs parametric amplifiers (PAs) as the wave splitting and mixing elements. The quantum behavior stems from the PAs, which produce

Quantum Entangled Interferometers.

A new type of quantum entangled interferometer was recently realized that employs parametric amplifiers as the wave splitting and recombination elements. The quantum entanglement stems from the

Nonlinear interferometers in quantum optics

We review the main works in the field of nonlinear interferometers, which has been developing ever since the start of nonlinear optics and has seen growing interest in recent years due to the

A theory of two-photon-state generation via four-wave mixing in optical fibers

Four-wave mixing (FWM) has long been studied, especially in the context of isotropic materials, e.g., optical fibers [1, 2]. Generally speaking, it is a photon-photon scattering process, during which

Quantum imaging with undetected photons

A quantum imaging concept based on induced coherence without induced emission is introduced and experimentally demonstrated, a prototype in quantum information—knowledge can be extracted by, and about, a photon that is never detected.
