Single-Photon Detection System for Photonic Quantum Technologies
Abstract
A central requirement in quantum technologies is the ability to detect photons with little or no excess noise and high timing resolution for applications including quantum communication schemes with unconditional security, quantum repeater networks, precision sensor networks, and photonic quantum simulation. To advance these technologies, we require high-speed, high-efficiency, low-noise single photon detectors for the telecom wavelength region. We therefore propose to construct a multi-channel superconducting single photon detector (SNSPD) system with high-speed time-tagging electronics. The proposed detector system would greatly accelerate research in key areas: photonic quantum simulation and machine learning; quantum communication schemes with 10x-100x speeds than previously demonstrated (10-100 Mbps) and their deployment into a Boston-area fiber network; the development of ultra-bright single photon sources; and quantum repeater networks with frequency conversion to the telecom band.
