作为量子多播网络的一个典型例子，研究了蝴蝶网络上的量子网络编码。在限制窃听者功率的条件下，提出了一种适用于蝴蝶网络的安全量子网络码。该协议在没有攻击的情况下当然会传输量子态。当窃听者窃听蝴蝶网络中的一个信道时，我们还证明了共享随机性作为额外资源的保密性，并导出了通过公共经典通信发送的信息。我们的协议不需要验证过程，这确保了单发安全性。
Quantum network coding on the butterfly network has been studied as a typical example of quantum multiple cast network. We propose a secure quantum network code for the butterfly network with free public classical communication in the multiple unicast setting under restricted eavesdropper’s power. This protocol certainly transmits quantum states when there is no attack. We also show the secrecy with shared randomness as additional resource when the eavesdropper wiretaps one of the channels in the butterfly network and also derives the information sending through public classical communication. Our protocol does not require verification process, which ensures single-shot security.
