摘要
量子密钥分配是量子密码学最成功的应用。如何产生高效的量子信号,是量子密钥分配系统安全运行的关键。文中简要介绍了量子信号的概念,给出了几种产生量子信号的常用方法,并简要分析了这些信号应用于量子密钥分配的可行性。
Quantum key distribution （QKD） is a successful application of quantum cryptography. The key to a sound QKD system is how to generate highly effective quantum signal. This paper presents the conception of quantum signal and several common methods for generating quantum signals. And the feasibility of the application of such quantum signal in QKD system is discussed.
