中文摘要：

为长距离量通讯的最大的障碍在光子上是隧道损失和隧道噪音。在这篇论文，解决这个问题的一个方法用检查和力量插入(国际新闻学会) 被分析。量通讯可以用这种技术在任意地长的距离上被建立，这被证明。要求的资源的数量是距离的多项式功能。国际新闻学会作为一种一般技术被建议延长量秘密发送消息的安全直接通讯在一条量隧道上直接被播送。

英文摘要：

The biggest obstacle for long distance quantum communication is the channel loss and the channel noise on photons. In this paper, a method to solve this problem was analyzed using inspection and power insertion （IPI）. It is proved that quantum communication may be established over arbitrarily long distance using this technology. The amount of resources required is a polynomial function of the distance. IPI is proposed as a general technique to prolong quantum secure direct communication where secret messages are transmitted directly over a quantum channel.
