In this research, we prepared two themes as a geotropism which attains the research subject. One is "The security of quantum key distribution using the real system" and the other is "the foundation of quantum information theory".If it says about the real system, the situation of a quantum information theory will have accomplished the remarkable variation during the research.In particular, quantum key distribution system arrived at the region of utilization. And related software is remarked on the system.Therefore we propose two important research results. One is secure QKD protocol under "using week coherent quantum information and quantum erasure-channel". And another is error-correcting system that achieves privacy amplification simultaneously.On the later-subject, we put other quantum protocols into the research field, and we have guessed how we should consider the theoretical hypothesis to be important at present. In particular, we evaluated and proposed quantum bit commitment protocol, QKD protocol with multi-photon protocols. Though the researches, we conclude that it is important for construction of secure quantum protocols to arrange the assumption of availability of entanglement states, of realization of quantum states, of existence of quantum memory, of quantum channel models.

在这项研究中，我们准备了两个主题，作为一个属于研究主题的地球运动。一种是“使用真实系统的量子密钥分布的安全性”，另一个是“量子信息理论的基础”。如果它说明了实际系统，那么量子信息理论的情况将在研究过程中实现显着差异。特别是，量子密钥分布系统到达了利用区域。并在系统上进行了相关软件的评论。因此，我们提出了两个重要的研究结果。一种是“使用周相干量子信息和量子擦除通道”下的安全QKD协议。另一个是同时实现隐私放大的错误校正系统。在后面的主题中，我们将其他量子协议放入了研究领域，我们猜测我们应该如何将理论假设视为目前很重要。特别是，我们评估并提出了具有多光子协议的QKD协议，并提出了量子位承诺协议。尽管研究了，但我们得出的结论是，对于安排纠缠状态的可用性，实现量子状态，存在量子记忆，量子存储器，量子通道模型的可用性的假设至关重要。
