BB84协定

BB84协定^[1]^[2] 是由 Charles Bennett（英语：Charles H. Bennett (computer scientist)） and Gilles Brassard（英语：Gilles Brassard）在 1984 年时所发展出的一种量子密钥分发方式。它也是第一个量子密码学协定。^[3] 根据量子特性，如果想要鉴别的资讯处于双态并非正交(见 不可克隆原理)且可身份验证的^[4]公开古典通道者，只可能在付出干扰信号本身的代价后，才有可能被取得，因此这个协定是可证安全的（英语：Provable security）。这个协定经常被作为一种安全地从一方传递到另外一方来作为一次性密码本的方法。
