Blind quantum computation (BQC) allows a client without enough quantum technologies to delegate her quantum computation to a remote quantum server, while keeping her input, output and algorithm secure. In this paper, we propose a universal single-server and almost-classical-client BQC protocol. In this protocol, the client interfaces with only one server and the only ability of the client required is to get particles from the trusted center and forward them to the server. We present an analysis of this protocol and modify it to a universal single-server and fully-classical-client BQC protocol by improving the ability of the trusted center. Based on our protocols and recent works, a new ‘Cloud + Certificate Authority (CA)’ style is proposed for the BQC.

盲量子计算 (BQC) 允许没有足够量子技术的客户端将其量子计算委托给远程量子服务器，同时保持其输入、输出和算法的安全。在本文中，我们提出了一种通用的单服务器和几乎经典的客户端 BQC 协议。在该协议中，客户端仅与一台服务器接口，客户端所需的唯一能力是从可信中心获取粒子并将它们转发到服务器。我们对该协议进行了分析，并通过提高可信中心的能力将其修改为通用的单服务器和完全经典的客户端 BQC 协议。根据我们的协议和最近的工作，为 BQC 提出了一种新的“云 + 证书颁发机构 (CA)”样式。
