盲量子计算（BQC）使拥有少量量子技术的客户端能够将其量子计算委托给具有强大量子计算能力的服务器，而服务器对客户端的量子输入，输出和算法一无所知。在本文中，我们提出了一种基于量子电路模型的单服务器BQC协议，通过用旋转算子的组合来替换任何量子门。引入了陷阱量子电路，以及旋转算子的组合，使得服务器不知道量子算法。客户端只需要执行操作X和Z，而服务器端诚实地执行旋转操作。
Blind quantum computation (BQC) enables the client, who has few quantum technologies, to delegate her quantum computation to a server, who has strong quantum computabilities and learns nothing about the client’s quantum inputs, outputs and algorithms. In this article, we propose a single-server BQC protocol with quantum circuit model by replacing any quantum gate with the combination of rotation operators. The trap quantum circuits are introduced, together with the combination of rotation operators, such that the server is unknown about quantum algorithms. The client only needs to perform operations X and Z, while the server honestly performs rotation operators.
