BB84 Quantum Key Distribution System based on Silica-Based Planar Lightwave Circuits

Abstract

We constructed an optical interferometer for a Bennett-Brassard quantum key distribution system using integrated optics based on planar lightwave circuit technology, and tested its operation and stability. Experimental results show that this interferometer is useful in implementing a practical quantum key distribution system.
