对“Holevo极限下的量子密钥分发”一文的评论

Comment on "Quantum Key Distribution in the Holevo Limit"

A. Fahmi, M. Golshani

摘要:

Cabello在一封信中提出了一个满足Holevo极限的量子密钥分发(QKD)协议。在这篇评论中,我们表明Eve可以使用一个简单的计划来区分量子密钥,而不会被Alice和Bob发现。在下文中,我们表明我们的方法并不局限于Cabello协议。注意到我们的窃听方法,似乎Mor的论点正交态的不可克隆原则是不够一般,以避免窃听。

英文摘要:

In a Letter, Cabello proposed a quantum key distribution (QKD) Protocol which attended to Holevo limit. In this comment, we show that Eve could use a simple plan to distinguish among quantum keys, without being detected by Alice and Bob. In following, we show that our approach is not restricted to Cabello Protocol. With attention to our Eavesdropping approach, it seems that Mor's arguments for no-cloning principal for orthogonal states is not general enough to avoid eavesdropping.
