Research output: Contribution to journalConference articlepeer-review


Low-loss, ultrafast photon routing is an enabling technology for optical quantum information processing. We demonstrate a 20 GHz, all-optical switch for 1590-nm photons from a heralded single-photon source, achieving a signal-to-noise ratio of 140:1.
