Engineered quantum dot single-photon sources

Abstract

Fast, high efficiency, and low error single photon sources are required for\nimplementation of a number of quantum information processing applications. The\nfastest triggered single photon sources to date have been demonstrated using\nepitaxially grown semiconductor quantum dots (QDs), which can be conveniently\nintegrated with optical microcavities. Recent advances in QD technology,\nincluding demonstrations of high temperature and telecommunications wavelength\nsingle photon emission, have made QD single photon sources more practical. Here\nwe discuss the applications of single photon sources and their various\nrequirements, before reviewing the progress made on a quantum dot platform in\nmeeting these requirements.\n
