Superconducting nanowire single-photon detector (SNSPDs) can work in free running mode with high detection efficiency, low dark counts rate, high speed and low jitter. These unique properties make SNSPDs strong candidates for quantum optics. For example, we are using SNSPDs to measure the efficiency of a correlated photon-pair source. Using SNSPDs, such measurements can be many orders-of-magnitude faster than using other photodetectors (such as avalanche photodiodes working in Geiger mode).
Our quantum computing effort currently focuses on developing superconductive detectors that interact with ion traps or neutral-atomic systems to readout their internal quantum state. This is a new project in collaboration with Profs. Isaac Chuang and Vladan Vuletic, and we are currently seeking a post-doc interested in joining this team.
