Abstract: Blind quantum computation that combines notions of quantum cryptography and quantum computation can fulfill quantum computation by a client with limited or even no quantum computational power with the help of an unreliable quantum server and keep the privacy of the client′s algorithm and the data. In this article, the principles and unconditional security of blind quantum computation are reviewed. And the researchers also explore several universal protocols of blind quantum computation, analyze their efficiency and introduce the physical implementation of blind quantum computation which is based on the technology of measurementbased computation. Finally, future prospect of blind quantum computation is discussed.
