N2 - Scalable photonic quantum technologies require on-demand single-photon sources with simultaneously
high levels of purity, indistinguishability, and efficiency. These key features, however, have only been
demonstrated separately in previous experiments. Here, by s-shell pulsed resonant excitation of a Purcellenhanced
quantum dot-micropillar system, we deterministically generate resonance fluorescence single
photons which, at π pulse excitation, have an extraction efficiency of 66%, single-photon purity of 99.1%,
and photon indistinguishability of 98.5%. Such a single-photon source for the first time combines the
features of high efficiency and near-perfect levels of purity and indistinguishabilty, and thus opens the way
to multiphoton experiments with semiconductor quantum dots.
