TLDR
Pulsed resonance fluorescence has been anticipated as the optimum condition for the deterministic generation of high-quality photons with vanishing effects of dephasing and is generated from a single, microcavity-embedded quantum dot under s-shell excitation with 3 ps laser pulses.Abstract:
Pulse-excited resonance-fluorescence single-photons are generated on demand from a single quantum dot embedded in a microcavity under s-shell excitation with an ultrafast laser source.read more

Stimulated Generation of Indistinguishable Single Photons from a Quantum Ladder System
TL;DR: In this article , a two-photon excitation of the biexciton followed by a precisely timed stimulation pulse results in very low timing jitter of the photons, and consequently, high indistinguishability.

Measurement of subpicosecond time intervals between two photons by interference.
TL;DR: A fourth-order interference technique has been used to measure the time intervals between two photons, and by implication the length of the photon wave packet, produced in the process of parametric down-conversion.
