The heat is on: Towards the realization of non-cryogenic photonic quantum technologies

Abstract

Solid-state devices capable of emitting single photons on demand are poised to allow the development of several photonic quantum technologies. Although high-performance devices have been reported in laboratory settings, the vast majority of experimental demonstrations performed to date have required the assistance of cryogenic cooling. In this perspective article we discuss the general progress and future challenges for the development of single photon emitters capable of operation at higher temperatures: negating the need for costly and cumbersome cryogenic cooling systems and their related vacuum requirements.
