在量子密钥分发的后处理过程中,采用了经典通信方式。由于量子密钥分发的安全性是基于量子力学原理的,因此直观地说,密钥只能从量子态中导出。我们发现,经典的通信被错误地用于所谓的量子对话型协议。在这些协议中,公共通信用于传输秘密消息。我们的计算表明,一半的爱丽丝和鲍勃的秘密消息是通过经典信道泄漏。通过应用Holevo界,我们可以看到量子对话类型协议中所要求的量子效率是不可实现的。
Classical communications are used in the post-processing procedure of quantum key distribution. Since the security of quantum key distribution is based on the principles of quantum mechanics, intuitively, the secret key can only be derived from the quantum states. We find that classical communications are incorrectly used in the so-called quantum dialogue type protocols. In these protocols, public communications are used to transmit secret messages. Our calculations show that half of Alice's and Bob's secret message is leaked through the classical channel. By applying the Holevo bound, we can see that the quantum efficiency claimed in the quantum dialogue type of protocols is not achievable.
