Joshua C BienfangJoshua C. Bienfang is a member of the Quantum Optics Group at the National Institute of Standards and Technology (NIST), whose mission is the study non-classical light and detectors for use in absolute metrology, quantum-enabled measurements, quantuminformation, and tests of fundamental physics. Josh's recent work in single-photon detection systems has resulted in unprecedented efficiency and noise performance in fast gated detectors, and advances in fast quenching of Si devices to reduce afterpulsing. As an NRC post-doc, Josh conducted some of the earliest investigations of high-speed free-space quantum key distribution and demonstrated a scalable system with orders-of-magnitude improvement in speed over prior techniques. As a graduate student at the University of New Mexico, Josh studied laser frequency stabilization and nonlinear optics, and built a 20 W sodium-guidestar source for adaptive optics systems, the first high-power continuous-wave source of this kind.
