我们研究了一般家庭的量子协议的位置验证，并提出了一类攻击的Clifford层次的基础上。这些攻击优于目前的策略，基于端口的隐形传态的一大类实际协议。然后，我们介绍的交错产品协议，位置验证的计划，只涉及的准备和测量的单量子位状态，最好的攻击有一个复杂性指数的经典位传输的数量。
We study a general family of quantum protocols for position verification and present a class of attacks based on the Clifford hierarchy. These attacks outperform current strategies based on port-based teleportation for a large class of practical protocols. We then introduce the interleaved product protocol, a scheme for position verification involving only the preparation and measurement of single qubit states for which the best available attacks have a complexity exponential in the number of classical bits transmitted.
