In this paper, we consider the problem of entanglement verification across the quantum memories of any two nodes of a quantum network. Its solution can be a means for detecting (albeit not preventing) the presence of intruders that have taken full control of a node, either to make a denial-of-service attack or to reprogram the node. Looking for strategies that only require local operations and classical communication (LOCC), we propose two entanglement verification protocols characterized by increasing robustness and efficiency.

具有篡改节点的量子网络中的纠缠验证

在本文中，我们考虑了跨量子网络任意两个节点的量子存储器的纠缠验证问题。它的解决方案可以是一种检测（尽管不能阻止）入侵者存在的手段，这些入侵者已经完全控制了一个节点，无论是进行拒绝服务攻击还是重新编程节点。寻找只需要本地操作和经典通信 (LOCC) 的策略，我们提出了两种以提高鲁棒性和效率为特征的纠缠验证协议。
