论文摘要
我们提出了一个不信任接收器的受控量子传送的设备独立分析。我们表明，真正的三方非局部性的概念使我们能够在这种情况下证明控制能力。通过考虑以去极化噪声为特征的设备上的特定对抗攻击策略，我们发现控制能力是真正三方非局部性的单调增加的功能。这些结果与构建实用量子通信网络有关，并且还阐明了非局部性在多部分量子信息处理中的作用。
We present a device independent analysis of controlled quantum teleportation where the receiver is not trusted. We show that the notion of genuine tripartite nonlocality allows us to certify control power in such a scenario. By considering a specific adversarial attack strategy on a device characterized by depolarizing noise, we find that control power is a monotonically increasing function of genuine tripartite nonlocality. These results are relevant for building practical quantum communication networks and also shed light on the role of nonlocality in multipartite quantum information processing.
