量子网络的量子相干性
Quantum Anonymity for Quantum Networks
摘要：
我们提出了第一个量子匿名通知（QAN）协议，该协议引入了匿名性，为量子网络中的匿名安全量子通信铺平了道路。QAN协议的应用范围从多方量子计算到量子互联网。我们利用QAN协议提出了一个$n$节点量子网络中的匿名量子私有比较协议。该协议可以在其余$n-k$方和半诚实第三方的帮助下比较任何$2 \leq k \leq n$方的私有信息。这些协议具有无痕属性，即，编码操作不能追溯到它们的原始来源。安全性分析表明，该协议对外部攻击者和恶意参与者具有较强的鲁棒性。
英文摘要：
We present the first quantum anonymous notification (QAN) protocol that introduces anonymity and paves the way for anonymous secure quantum communication in quantum networks. QAN protocol has applications ranging from multiparty quantum computation to quantum internet. We utilize the QAN protocol to propose an anonymous quantum private comparison protocol in an $n$-node quantum network. This protocol can compare private information of any $2 \leq k \leq n$ parties with the help of the remaining $n-k$ parties and a semi-honest third party. These protocols feature a traceless property, i.e., encoding operations cannot be traced back to their originating sources. Security analysis shows that this protocol is robust against external adversaries and malicious participants.
