仅执行单量子比特门的用户的盲量子计算

Blind quantum computation for a user who only performs single-qubit gates

Qin Li, Chengdong Liu, Yu Peng, Fang Yu, Cai Zhang

摘要:

盲量子计算(BQC)允许具有有限量子能力的用户在远程量子服务器的帮助下完成量子计算任务,使得用户的输入、输出甚至算法可以对服务器保持隐藏。到目前为止,BQC主要有两种模式。一个是客户端只需要准备Broadbent,Fitzsimons和Kashefi发起的单量子位的能力,另一个是客户端只需要执行Morimae首先给出的单量子位测量。本文提出了一种新的BQC模型,在该模型中,用户只需要实现几个单量子位门。我们还提出了一个具体的BQC协议,用户只需要实现两种单量子比特门,以显示所提出的模型的可行性。这种电路模型非常灵活,因为能够执行不同单量子位门的各种用户都可能有机会实现BQC。此外,与其他两种模型相比,它可能更适合于在一些实验装置中的实际实现,如囚禁离子和超导系统,因为单量子位门是这种系统中最精确的操作。

英文摘要:

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.
