摘要
本文给出了整个传输的互信息、量子比特误码率(QBER)的正确计算。指出了 Wójcik 论文 [Phys. Rev. Lett. {\bf 90}, 157901(2003)] 中关于互信息、量子比特误码率(QBER)与安全性的一般结论的错误。

备注
In this paper the correct calculations of the mutual information of the whole transmission, the quantum bit error rate (QBER) are presented. Mistakes of the general conclusions relative to the mutual information, the quantum bit error rate (QBER) and the security in W\'{o}jcik's paper [Phys. Rev. Lett. {\bf 90}, 157901(2003)] have been pointed out. Also I hope experts can give me some help in addressing the question I present in this paper
