Linear optics with photon counting is a prominent candidate for practical quantum
computing. The protocol by Knill, Laflamme, and Milburn [2001, Nature (London) 409, 46] …

Multiphoton interference reveals strictly nonclassical phenomena. Its applications range
from fundamental tests of quantum mechanics to photonic quantum information processing …

This review covers the latest developments in continuous-variable quantum-state
tomography of optical fields and photons, placing a special emphasis on its practical aspects …

Conventional nonlinear spectroscopy uses classical light to detect matter properties through
the variation of its response with frequencies or time delays. Quantum light opens up new …

The time-frequency degree of freedom is a powerful resource for implementing high-
dimensional quantum information processing. In particular, field-orthogonal pulsed temporal …

Broadband multimode squeezers constitute a powerful quantum resource with promising
potential for different applications in quantum information technologies such as information …

The ability to determine the joint spectral properties of photon pairs produced by the
processes of spontaneous parametric downconversion (SPDC) and spontaneous four-wave …

We study the conditional preparation of single photons based on parametric
downconversion, where the detection of one photon from a given pair heralds the existence …

We study theoretically the generation of photon pairs by spontaneous four-wave mixing
(SFWM) in photonic crystal optical fiber. We show that it is possible to engineer two-photon …

Frequency conversion (FC) and type-II parametric down-conversion (PDC) processes serve
as basic building blocks for the implementation of quantum optical experiments: type-II PDC …
