Japan is poised to start work on global quantum key distribution service and associated infrastructure.

Quantum Communications Link Technology that realizes high-speed, long-distance, and high-availability links in quantum cryptographic communication networks;.

Wide-area network construction and operation technology, which manages and controls wide-area and large-scale quantum cryptographic communication networks.

Quantum encryption sees keys encoded in the quantum state of a particle, often an entangled photon.

As quantum mechanics means that if a quantum state is measured, it is changed, it is possible to know if a quantum key has been observed.
