Scheme design and improvement of quantum key distribution network
Yang Juntao · Chinese Journal of Quantum Electronics · 2005
For the practical and commercial use of quantum cryptography, we need to distribute keys among many users. We introduce E91 quantum key distribution scheme, which is based on EPR pair. Then, based on the E91 scheme, we propose a quantum key distribution scheme on quantum cryptography network with many users where communications among any users can occur; also, combining with WDM technology, we made an improvement on the cascaded loop quantum key distribution network scheme.
