AI 中文摘要
量子网络代表着安全通信的未来，可通过量子信息交换实现全新能力。然而，这些网络需要安全、高保真的量子通信信道，且要求每个参与节点都是真正的量子设备。目前，尚无可靠方法验证接入量子网络的客户端是否真正具备量子计算能力，以及是否通过健壮信道连接。本研究提出一种客户端验证协议，作为量子能力证明握手协议，可保护量子网络免受经典欺骗者、有噪声量子计算机，以及通过有噪声或不安全信道接入网络的真正量子设备的攻击。我们通过在擦除、退相和退极化噪声模型下的数值模拟验证了该协议的有效性。
英文摘要
Quantum networking represents the future of secure communication, enabling fundamentally new capabilities through quantum information exchange. However, these networks require secure, high-fidelity quantum communication channels, and they require every participating node to be a genuine quantum device. Currently, there is no reliable method to verify whether clients entering a quantum network truly possess quantum computational capability and are connecting over robust channels. In this work, we introduce a client-validation protocol that functions as a proof-of-quantum-capability handshake. Our protocol secures a quantum network against classical spoofers, noisy quantum computers, and genuine quantum devices connecting with the network over noisy or insecure channels. We validate the efficacy of this protocol through numerical simulations under erasure, dephasing, and depolarizing noise models.
