本文描述了基于量子力学原理在两方之间共享随机秘密数字串的量子密钥分发（QKD）的安全性。 BB84协议中隐含地使用了Colderbank-Shor-Steane量子码，使得该码的保真度统一，并且共享密钥与获得的数据之间的互信息接近于零。在 BB84 协议中，发送方发送的数字被编码为正交基或共轭基。这些 CSS 代码实现了称为香农率的更高速率。
This paper describes the security of quantum key distribution (QKD) to share a random secret string of digits between two parties based on the principle of quantum mechanics. A Colderbank-Shor-Steane quantum code had been implicitly used in the BB84 protocol, which makes fidelity of this code to unity and the mutual information between the shared key and the data obtained approaches zero. In the BB84 protocol, the sender transmits digits from which encoded into an orthogonal basis or the conjugate basis. These CSS codes achieve a higher rate called as Shannon rate.
