论文摘要
盲量量计算（BQC）协议使量子算法能够在第三方量子剂上执行，同时保持数据和算法机密。先前关于基于测量的BQC的建议需要准备高度纠缠的群集状态。在本文中，我们表明没有必要的要求。我们的协议仅需要在授权的量子代理之间进行预共享的钟形对，并且在执行过程中不需要任何经典或量子信息交换。通过消除对通用群集状态的需求，我们的建议比以前的提案所需的量子资源更少。
Blind quantum computation (BQC) protocols enable quantum algorithms to be executed on third-party quantum agents while keeping the data and algorithm confidential. The previous proposals for measurement-based BQC require preparing a highly entangled cluster state. In this paper, we show that such a requirement is not necessary. Our protocol only requires pre-shared bell pairs between delegated quantum agents, and there is no requirement for any classical or quantum information exchange between agents during the execution. Our proposal requires fewer quantum resources than previous proposals by eliminating the need for a universal cluster state.
