BB84 Quantum Key Distribution System based on Silica-Based Planar Lightwave Circuits
Yoshihiro Nambu, Takaaki Hatanaka, Kazuo Nakamura
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…
Single-photon interference over 150-km transmission using silica-based integrated-optic interferometers for quantum cryptography
Tadamasa Kimura, Yoshihiro Nambu, Takaaki Hatanaka +3
We have demonstrated single-photon interference over 150 km using time-division interferometers for quantum cryptography, which were composed of two integrated-optic asymmetric Mac…
Planar lightwave circuits for quantum cryptographic systems
Yoshihiro Nambu, Takaaki Hatanaka, Kazuo Nakamura
We propose a quantum cryptographic system based on a planar lightwave circuit (PLC) and report on optical interference experiments using PLC-based unbalanced Mach-Zehnder interfero…
