Quantum key distribution (QKD)

Photons

Eavesdropper X

By encoding the signal into photons, one can detect any hacking attacks. Thus one can ensure unbreakable security even by future technologies.

- The world fastest QKD systems are installed into a Tokyo area of JGN-X.

- Reliability test and security certification are going on.
