  Blind quantum computation (BQC) allows a user who has limited quantum
capability to complete a quantum computational task with the aid of a remote
quantum server, such that the user's input, output, and even the algorithm can
be kept hidden from the server. Up to now, there are mainly two models of BQC.
One is that the client just needs the ability to prepare single qubits
initiated by Broadbent, Fitzsimons, and Kashefi, and the other is that the
client only needs perform single-qubit measurements first given by Morimae. In
this paper, we put forward a new model of BQC in which a user only requires
implementing a few single-qubit gates. We also propose a specific BQC protocol
where a user only needs to implement two kinds of single-qubit gates to show
the feasibility of the presented model. This circuit model is quite flexible
since various users with the ability to perform different single-qubit gates
may all have the chance to achieve BQC. Furthermore, compared with the other
two models, it may be more suitable for practical implementation in some
experimental setups such as trapped ions and superconducting systems since the
single-qubit gates are the most exact operations in such systems.
