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

Pulsed Rabi Oscillations in Quantum Two-Level Systems: Beyond the Area Theorem
TL;DR: In this paper, the authors investigated the breakdown of the Area Theorem as both the pulse length becomes non-negligible and for certain pulse areas, using simple quantum trajectories, they provided an analytic approximation to the photon emission dynamics of a two-level system.

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.
