ICTs are expected to reduce their own equipment and service energy consumption and mitigate GHG emissions through use of ICTs in other relevant sectors. Standardization activities of green ICTs in ITU...
Implementation of a High-Speed Quantum Key Distribution System for Metropolitan Networks
Quantum cryptography
2010/6/9
Improvement of QKD performance, particularly on key generation rate, has been required to meet current network traffic. A high-speed QKD system should be equipped with low loss receivers with high vis...
We demonstrate the first 10GHz clock-rate, differential-phase-shift-keyed quantum key distribution system on a 10Gb/s multi-user WDM-PON network. A dual feeder fiber scheme is used to reduce spontaneo...
Quantum Key Distribution offers the promise of secure communication at unprecedented security level. Secure systems can be implemented by standard optical communication components - if done right. We ...
