可靠性函数给出了通信信道中错误概率指数收敛到零的速率。本文给出了量子纯态信道可靠性函数的界，使人联想到相应的经典界。这特别提出了量子无噪声信道编码定理的另一种证明，它不使用典型子空间的概念。以二进制量子信道为例进行了详细的讨论。
The reliability function gives the rate of exponential convergence to zero of the error probability in a communication channel. In this paper bounds for the reliability function of a quantum pure state channel are given, reminiscent of the corresponding classical bounds. This in particular suggests an alternative proof of the coding theorem for quantum noiseless channel, which would make no use of the notion of typical subspace. Example of binary quantum channel is considered in some detail.
