Using coherent quantum communication to enhance the security of intra-city cryptography.

Coherent Quantum Key Distribution

Our quantum key distribution systems are based on coherent telecommunication technology. Quantum states are distributed with state-of-the-art rates of 10 Gbaud via an optical fiber link, enabling the fastest key generation rates for metropolitan security applications. The characteristics of our research system can be found in the following table.
