High Speed Quantum Key Distribution over Optical Fiber Network System
Xiao Tang, Lijun Ma, Alan Mink
NIST has developed a number of complete fiber-based high-speed quantum key distribution QKD)systems that includes an 850 nm QKD system for a local area network (LAN), a 1310 nm QKD system for a metropolitan area network (MAN), and a 3-node quantum network controlled by a network manager. This paper discusses the key techniques used to implement these systems, which include polarization recovery, noise reduction, frequency up-conversion detection based on PPLN waveguide, custom high-speed data handling boards, and quantum network management. Using our quantum network, a QKD secured video surveillance application has been demonstrated. Our intention is to show the feasibility and sophistication of QKD systems under current technology development.
