TL;DR: In this article, a truly remote, independent InGaAs quantum dots are tuned to the same energy using large applied electric fields of up to −500 kV cm−1, allowing for two-photon interference of their emission under coincidence gating, and opens up the possibility of transferring quantum information between remote solid-state sources.

TL;DR: The realization of an electrically driven source of entangled photon pairs, consisting of a quantum dot embedded in a semiconductor light-emitting diode (LED) structure, shows its potential function as an on-demand source without the need for a complicated laser driving system, and is at present the best source on which to base future scalable quantum information applications.

TL;DR: In this paper, a technique to control the energetic splitting of two quantum states using a vertical electric field, facilitating the observation of coherent coupling between them, was described, leading to the generation of entangled photon pairs.

TL;DR: Measurements show that entanglement of the photon pair is robust to the dephasing of the intermediate exciton state responsible for the first-order coherence time of either single photon.

TL;DR: It is concluded that emission of photon pairs by a typical quantum dot with finite polarization splitting is in fact entangled in a time-evolving state, and not classically correlated as previously regarded.
