在盲量子计算（BQC）中，客户端将其量子计算委托给具有通用量子计算机的服务器，该服务器对客户端的私有信息一无所知。在基于测量的BQC模型中，通常使用纠缠态来实现量子计算。然而，如何在实验中产生大规模的纠缠态是一个具有挑战性的问题。在基于电路的BQC模型中，单量子比特门可以精确地实现，但纠缠门是概率成功的。在某些系统中，用确定性方法实现纠缠门仍然是一个挑战。为了解决以上两个问题，我们提出了第一个基于测量和电路的混合通用BQC协议，其中客户端准备单量子比特状态，服务器执行通用量子计算。分析并证明了协议的正确性、盲性和可验证性。
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.
