An atomic system that can be addressed via a single optical mode, hereafter called a one-
dimensional atom, is central for many applications in optical quantum technologies. A cavity …

Single photon source is indispensable for realization of photon based quantum
communication technologies such as quantum key distribution (QKD). Weak coherent pulse …

Ideal photonic quantum memories can store arbitrary pulses of light with unit efficiency. This
requires operating in the adiabatic regime, where pulses have a duration much longer than …

A quantum network at the global scale will consist of stationary nodes linked via photonic
channels. Single atoms in optical cavities are a prime candidate for building these nodes, as …

We derive a master equation for a superradiant medium which includes multilevel
interference between the individual scatterers. The derivation relies on the Born-Markov …

Optical quantum memories are crucial ingredients for a multitude of quantum network
protocols. In this thesis, the efficient absorption and emission of a single-photon polarization …

L'émission spontanée de lumière par un émetteur n'est pas un processus intrinsèque. D'une
part, il dépend de l'environnement électromagnétique. D'autre part, il dépend de la présence …
