摘　　要：受控非局域量子门操作揭示了量子网络中控制方与非局域门操作方之间的合作与控制关系,是构建多方量子计算网络的关键,其安全性保证来源于量子纠缠资源.针对供应商以经典-量子混合资源代替量子纠缠资源的行为,本文提出了一种受控非局域CNOT量子门的设备无关验证方案,并在Svetlichny不等式不适用的情况下设计了Svetlichny-type不等式,有效检验了非局域门操作中纠缠资源利用情况.我们的方案为未来构建安全的分布式量子计算网络提供了理论基础.Controlled non-local quantum gate operations reveal the cooperative and supervisory relationships of the controller and the non-local gate operators in a quantum networks,which is an essential feature for building multi-party quantum computing networks,and their security relies on quantum entanglement resources.To understand the behavior of vendors who substitute quantum entanglement resources with classical-quantum hybrid resources,this paper proposes a device-independent verification scheme for controlled non-local CNOT quantum gates.Moreover,it formulates a Svetlichny-type inequality to conduct an effective verification of the utilization of entanglement resources in nonlocal gate operations,particularly in instances where the Svetlichny inequality is not applicable.Our scheme offers a theoretical foundation for constructing secure distributed quantum computing networks in the future.
