Blind Quantum Computation With Hybrid Model

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 (x(i)) over right arrow to the server and then the sever performs a corresponding function operation F-i((x(i)) over right arrow), 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 X and Z operators.
