论文摘要
盲量量子计算(BQC)允许具有有限量子能力的用户借助远程量子服务器来完成量子计算任务,从而可以将用户的输入,输出,甚至算法都可以隐藏在服务器中。到目前为止,主要有两种BQC模型。一个是,客户只需要能够准备由Broadbent,Fitzsimons和Kashefi发起的单量子位,另一个是客户只需要执行Morimae首先进行的单量测量。在本文中,我们提出了一种新的BQC模型,其中用户只需要实现一些单量门门。我们还提出了一个特定的BQC协议,其中用户只需要实现两种单量门门即可展示提出的模型的可行性。该电路模型非常灵活,因为具有执行不同单量门门的各种用户可能都有机会实现BQC。此外,与其他两个模型相比,它可能更适合在某些实验设置(例如捕获的离子和超导系统)中实现,因为单品门是此类系统中最精确的操作。
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.
