论文摘要
盲量量计算(BQC)允许具有有限量子功率的客户端将其量子计算任务委托给功能强大的服务器,并且仍然保持其输入,输出和算法私有。主要有两种有关BQC的模型,即基于电路的模型和基于测量的模型。此外,提出了一种称为Ancilla驱动的通用盲量计算(ADBQC)的混合模型,是通过结合基于电路的基于电路和基于测量的模型的性能来提出的,在该模型中,可以借助于单个Ancillae耦合到寄存器量的单一含量上的所有单一操作。但是,在ADBQC模型中,客户端的量子能力严格仅限于准备单量子位。如果客户端只能执行单量度测量值或一些简单的量子门,他可能还希望通过ADBQ将计算委托给远程服务器。本文通过为具有不同量子功能的客户提出两种类型的ADBQC协议来解决问题,并扩展了现有模型,例如执行单量测量值或单量门门。此外,在提出的两个ADBQC协议中,客户可以通过使用相应的可验证技术来检测服务器是否具有很高的可能性。
Blind quantum computation (BQC) allows a client with limited quantum power to delegate his quantum computational task to a powerful server and still keep his input, output, and algorithm private. There are mainly two kinds of models about BQC, namely circuit-based and measurement-based models. In addition, a hybrid model called ancilla-driven universal blind quantum computing (ADBQC) was proposed by combining the properties of both circuit-based and measurement-based models, where all unitary operations on the register qubits can be realized with the aid of single ancillae coupled to the register qubits. However, in the ADBQC model, the quantum capability of the client is strictly limited to preparing single qubits. If a client can only perform single-qubit measurements or a few simple quantum gates, he may also want to delegate his computation to a remote server via ADBQC. This paper solves the problem and extends the existing model by proposing two types of ADBQC protocols for clients with different quantum capabilities, such as performing single-qubit measurements or single-qubit gates. Furthermore, in the proposed two ADBQC protocols, clients can detect whether servers are honest or not with a high probability by using corresponding verifiable techniques.
