    "abstract": "We constructed an optical interferometer for a Bennett-Brassard quantum key\ndistribution system using integrated optics based on planar lightwave circuit\ntechnology, and tested its operation and stability. Experimental results show\nthat this interferometer is useful in implementing a practical quantum key\ndistribution system.",
