Single-photon detectors serve not only as sensitive receivers; they also represent a critical bridge between the quantum and classical worlds. The capabilities of single-photon detectors have a major impact on what is and is not feasible in developing new quantum technologies. We are interested in expanding the capabilities of single-photon detectors, and using them to demonstrate new applications in quantum information science. We have used radio-frequency interferometry to achieve ultra-sensitive high-speed single-photon detection [APL, 102, 141104 (2013)], an approach that achieves unprecedented efficiency and low-noise, and enables a variety of quantum key distribution and correlated-photon experiments. We have also developed low-latency single-photon detectors and used them to build random number generators for an all-photonic loophole-free test of the Bell inequalities [Opt. Exp. 26, 32788 (2018); PRL, 115, 250402 (2015)]. As detector performance advances, new methods and techniques are required for characterizing single-photon detectors. We are have developed powerful yet simple auto-correlation techniques [Opt. Exp. 25, 20352 (2017)] and we are pursuring further advances in detector characterizaiton, particularly for ultra-high time resolution superconducting single-photon nanowire detectors. Researchers interested single-photon detection, quantum cummunications, and high-speed electronics are encouraged to contact us about their research interests.
