Japan is poised to start work on global quantum key distribution service and associated infrastructure.
Toshiba today announced that Japan’s Ministry of Internal Affairs and Communications has named it the lead contractor on the project and that it aims to build a wide-area network that can accommodate over 100 quantum cryptographic devices and 10,000 users around the world.
The project aims to develop four things:
Quantum Communications Link Technology that realizes high-speed, long-distance, and high-availability links in quantum cryptographic communication networks;
Trusted Node Technology that ensures the robustness and tamper resistance(Note 5) of cryptographic key management systems, and improves the confidentiality, integrity, and availability of quantum cryptographic communications;
Quantum Relay Technology that extends distances and secure cryptographic key relays on the ground;
Wide-area network construction and operation technology, which manages and controls wide-area and large-scale quantum cryptographic communication ne ..
