Single photons are a fundamental element of most quantum optical technologies. The ideal
single-photon source is an on-demand, deterministic, single-photon source delivering light …

Photonic nanostructures provide a means of tailoring the interaction between light and
matter and the past decade has witnessed tremendous experimental and theoretical …

A quantum emitter efficiently coupled to a nanophotonic waveguide constitutes a promising
system for the realization of single-photon transistors, quantum-logic gates based on giant …

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 …

On-chip single-photon sources are key components for integrated photonic quantum
technologies. Semiconductor quantum dots can exhibit near-ideal single-photon emission …

Quantum key distribution (QKD) is the first quantum information task to reach the level of
mature technology, already fit for commercialization. It aims at the creation of a secret key …

Lasers and LEDs have a statistical distribution in the number of photons emitted within a
given time interval. Applications exploiting the quantum properties of light require sources …

Since the advent of quantum mechanics and the clear demonstration of the existence
of'matter waves', physicists have never failed to take advantage of concepts and theoretical …

We design several single-photon-sources based on the emission of a quantum dot
embedded in a semiconductor (GaAs) nanowire. Through various taper designs, we …

We describe the resonant excitation of a single quantum dot that is strongly coupled to a
photonic crystal nanocavity. The cavity represents a spectral window for resonantly probing …
