Abstract

Complete high-speed quantum key distribution (QKD) systems over fiber networks for campus and metro areas have been developed at NIST. The systems include an 850-nm QKD system for a campus network, a 1310-nm QKD system for metro networks, and a 3-user QKD network and network manager. In this paper we describe the key techniques used to implement these systems, including polarization recovery, noise reduction, frequency up-conversion detection based on PPLN waveguide, custom high-speed data handling and network management. A QKD-secured video surveillance system has been used to experimentally demonstrate these systems.
