In this paper, we propose a verifiable quantum cloud computation scheme based on blind quantum computation which effectively solves the privacy and verifiability problem for clients when interfacing with quantum computer in cloud computation. Different from most of present works (e.g. using brickwork state as resource state), we use cluster state with grid distributed structure to realize the universal and cryptographic calculation which is more suitable for the distributed architecture of cloud computation. Throughout the process, the random key is always held by the client that effectively promote the confidentiality. Moreover, we propose a new method to make the client Alice verifies the correctness of the results through only classical calculation. Security analysis shows that cloud server Bob can only obtain the dimension of input state and cluster state from the calculation, but cannot obtain any information of the input, the output and the algorithm. Dishonest Bob will be detected during the verification.

基于盲计算的可验证量子云计算方案

在本文中，我们提出了一种基于盲量子计算的可验证量子云计算方案，有效解决了客户端在云计算中与量子计算机接口时的隐私和可验证性问题。与目前大多数工作（例如使用砖砌状态作为资源状态）不同，我们使用具有网格分布式结构的集群状态来实现更适合云计算分布式架构的通用和密码计算。在整个过程中，随机密钥始终由客户端持有，有效地促进了机密性。此外，我们提出了一种新方法，让客户端 Alice 仅通过经典计算来验证结果的正确性。安全分析表明，云服务器Bob在计算中只能得到输入状态和集群状态的维度，而不能得到输入、输出和算法的任何信息。不诚实的鲍勃将在验证过程中被发现。
