Résumé
Single-photons are key elements of many future quantum technologies, be it for the realization of large-scale quantum communication networks, for quantum simulation of chemical and physical processes, or for connecting quantum memories in a quantum computer. Scaling quantum technologies will thus require efficient, on-demand, sources of highly indistinguishable single-photons. The seminar is devoted to the recent realization of such devices made of quantum dots in electrically controlled cavity structures. The achieved device allows on-demand, bright and ultra-pure single photon generation, with a source 20 times brighter than any source of equal quality. This new generation of sources opens the way to a new level of complexity and scalability in optical quantum manipulation.
