Description

Quantum communication, the distribution of entangled particles (usually photons), offers a fundamentally new physical resource for technological experimentation and development. We are developing tools and protocols for quantum networks, focusing mainly on sources, detectors, and timing synchronization systems that can enable entanglement distribution over metropolitan and long-haul fiber links. Beyond entanglement sources and synchronization systems, we have a particular interest in single-photon detection systems. 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 [Applied Physics Letters 118, 134002 (2021)], an approach that achieves unprecedented count rates and enables a variety of quantum key distribution and correlated-photon experiments. 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 development and have a particular interest in room temperature photon-number resolving detectors and the possibilities offered by combining single-electron devices with single-photon devices.

Researchers interested single-photon detection, quantum cummunications, and semiconductor device design are encouraged to apply.
