TL;DR: It is shown that resonance fluorescence, i.e., the resonant emission of a coherently driven two-level system, can be realized with a semiconductor quantum dot and second-order correlation measurements further confirm nonclassical light emission.

TL;DR: In this paper, the Mollow triplet in the emission spectrum of a quantum dot was observed to be a readout modality for electron-spin states, which can be used for quantum key distribution or through post-selection to generate entangled photon pairs.

TL;DR: In this article, the first fabrication of (In,Ga)As/GaAs quantum dots with both vertical and lateral ordering forming a three-dimensional array was reported, and an investigation of the photoluminescence spectra from the ordered array of quantum dots, as a function of both temperature and optical excitation intensity, reveals both a lateral and vertical transfer of excitation.

TL;DR: In this paper, the authors reported results of time-resolved terahertz (THz) pulse spectroscopy experiments on laterally ordered chains of self-assembled InGaAs quantum dots photoexcited with 400nm, 100fs laser pulses.
