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.
