摘要
量子密码术要走向实用化,必须实现多用户间的量子密钥分配。首先介绍了基于EPR对的E91量子密钥分发方案。利用该协议,我们在现有量子密钥分发网方案的基础上提出了一种实现多用户网络下任意多个用户之间的密钥分发方案,并融合波分复用技术对级联式环型量子密钥分发网方案进行了改进。
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 tile 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.
