Highly efficient sources of single indistinguishable photons — •Niels Gregersen — DTU Fotonik, Technical University of Denmark, Kongens Lyngby, Denmark

Single-photon sources (SPSs) capable of emitting single indistinguishable photons are key components in optical quantum information processing. The SPS figures of merit include the efficiency є of the photon collection and the indistinguishability η of the emitted photons, and scalable optical quantum information processing requires that the product є η is increased very close to unity. In this presentation, I will review present SPS design strategies including the micropillar design and the photonic nanowire design, and I will discuss the potential for increasing є η towards unity.
