Abstract

In the past decades, generating single photons on demand with well defined quantum states and detecting them after photon-photon or photon-matter interaction are central to the area of quantum optics and quantum information science. The ability to detect light efficiently at the single photon level offers unprecedented opportunities for a wide range of applications, including long-distance quantum key distribution, light detection and ranging, photonic quantum computing, weak light detection for astronomy and bio-imaging.
