Abstract

Requirements and specifications of quantum key distribution (QKD) systems are examined particularly for metropolitanarea networks. A design of QKD system is considered to satisfy the specifications. BB84 protocol with decoy method is chosen. The unidirectional system based on planer light wave circuit for high speed operation is proposed for quantum transmission. Issues on system control such as clock synchronization and frame synchronization are discussed. Finally, decoy method is analyzed and demonstrated to guarantee the quantitative security of the final key in real systems.
