A hybrid universal blind quantum computation
Abstract In blind quantum computation (BQC) a client delegates her quantum computation to a server with universal quantum computers who learns nothing about the client's private information. In measurement based BQC model, entangled states are generally used to realize quantum computing. However, to generate a large scale entangled state in experiment becomes a challenge issue. In circuit based BQC model, single qubit gates can be realized precisely, but entangled gates are probabilistically successful. This remains a challenge to realize entangled gates with a deterministic method in some systems. To solve above two problems, we propose the first hybrid universal BQC protocol based on measurements and circuits, where the client prepares single qubit states and the server performs universal quantum computing. We analyze and prove the correctness, blindness and verifiability of the proposed protocol.
