Blind quantum computation (BQC) allows a client who has a few quantum abilities to interact and delegate her quantum computation to a server that has strong quantum computabilities, while the server learns nothing about client’s quantum inputs, algorithms, and outputs. In this article, a new BQC protocol with hybrid model is proposed, using the combination of rotation operators to construct arbitrary quantum gate. Our BQC protocol is divided into two phases. In the first phase, a new kind of function operation is designed and defined, that is, the client sends the classical message [Formula: see text] to the server and then the sever performs a corresponding function operation [Formula: see text], which has been defined. In the second phase, a rotation operator or identity operator is implemented by quantum gate teleportation where the server can’t know which quantum gate has been teleported. Combining these two phases, the server has no idea about client’s quantum algorithms. When the server performs the corresponding operation honestly, the client only needs to perform [Formula: see text] and [Formula: see text] operators.

混合模型的盲量子计算

盲量子计算 (BQC) 允许具有少量量子能力的客户端进行交互并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、算法和输出一无所知。本文提出了一种新的混合模型BQC协议，利用旋转算子的组合构造任意量子门。我们的 BQC 协议分为两个阶段。第一阶段，设计并定义了一种新的函数操作，即客户端发送经典消息[公式：见正文]到服务器，然后服务器执行相应的函数操作[公式：见正文]，已定义。在第二阶段，旋转算子或恒等算子由量子门隐形传输实现，其中服务器无法知道哪个量子门已被隐形传输。结合这两个阶段，服务器不知道客户端的量子算法。当服务端诚实地执行相应的操作时，客户端只需要执行[公式：见文本]和[公式：见文本]运算符。
