In the context of quantum technologies, the generation and manipulation of single photons
has become a key element for applications such as quantum communication and quantum …

We review the current status of single-photon-source and single-photon-detector
technologies operating at wavelengths from the ultraviolet to the infrared. We discuss …

This review begins with an historical introduction to the field of nonlinear fiber optics and
then focuses on the propagation of short optical pulses inside optical fibers. The underlying …

Room-temperature, easy-to-operate quantum memories are essential building blocks for
future long distance quantum information networks operating on an intercontinental scale …

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 implement an ultrafast pulsed type-II parametric down conversion source in a
periodically poled KTP waveguide at telecommunication wavelengths with almost identical …

We review the concepts of temporal modes (TMs) in quantum optics, highlighting Roy
Glauber's crucial and historic contributions to their development, and their growing …

We introduce a novel time-frequency quantum key distribution (TFQKD) scheme based on
photon pairs entangled in these two conjugate degrees of freedom. The scheme uses …

Single photons are excellent quantum information carriers: they were used in the earliest
demonstrations of entanglement and in the production of the highest-quality entanglement …

Emission from a resonantly excited quantum emitter is a fascinating research topic within the
field of quantum optics and is a useful source for different types of quantum light fields. The …
