TL;DR: By s-shell pulsed resonant excitation of a Purcell-enhanced quantum dot-micropillar system, 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%.

TL;DR: In this article, a polarization-orthogonal excitation collection scheme is designed to minimize the polarization filtering loss under resonant excitation, achieving a single-photon efficiency of 0.60.

TL;DR: A temporal and spectral analysis reveals the pulsed resonance fluorescence single photons are close to the transform limit, which are readily useful for multiphoton entanglement and interferometry experiments.

TL;DR: In this article, a polarization-orthogonal excitation-collection scheme is designed to minimize the polarization-filtering loss under resonant excitation, and the authors demonstrate a polarized single-photon efficiency of 0.60+/-0.02 (0.56+/- 0.02), a singlephoton purity of 0975+/-

TL;DR: An experiment to test quantum interference, entanglement, and nonlocality using two dissimilar photon sources, the Sun and a semiconductor quantum dot on the Earth, which are separated by ∼150 million kilometers is reported.
