Towards Deterministic Photonic Entanglement Using Time-Frequency Control

Abstract

The project objectives were: first, to set up and operate a single-photon source based on a semiconductor microcavity quantum dot emitter, and to interface the emitted photons with a fiber-optic cavity network. Second, to interface the quantum dot source with a novel room temperature quantum memory with a broad spectral acceptance tailored to match the GHz-bandwidth photons characteristic of quantum dot emission. We made significant progress towards both of these objectives, although the move of the group to Imperial in 2018-19 and the COVID pandemic 2020 slowed work considerably without time to recover before the end of the project. Nevertheless, the outcomes are very promising, and we hope to be able to continue the work in the future.
