论文摘要
量子计算在解决其经典同行方面的某些问题方面具有相当大的优势。当前，开发了各种物理系统来构建量子计算机，但仍然具有挑战性，量子计算机的首次使用可能采用云样式。盲量量子计算（BQC）为具有有限量子功能的客户提供了解决方案，可以将其量子计算委派给远程量子服务器，同时保持输入，输出，甚至算法私有。在本文中，我们提出了三个具有身份认证的多方可验证的盲量计算（VBQC）协议，以处理量子网络中具有不同量子功能的客户，例如那些只能进行测量，准备单个Qubits或执行一些单个单一Qubit Gates的量子网络。它们对客户端友好且灵活，因为客户可以根据自己的量子设备来实现BQC，并抵制量子网络中的两个内部局外人攻击。此外，所有提出的协议都是可验证的，即客户可以验证其计算的正确性。
Quantum computing has considerable advantages in solving some problems over its classical counterpart. Currently various physical systems are developed to construct quantum computers but it is still challenging and the first use of quantum computers may adopt the cloud style. Blind quantum computing (BQC) provides a solution for clients with limited quantum capabilities to delegate their quantum computation to remote quantum servers while keeping input, output, and even algorithm private. In this paper, we propose three multi-party verifiable blind quantum computing (VBQC) protocols with identity authentication to handle clients with varying quantum capabilities in quantum networks, such as those who can just make measurements, prepare single qubits, or perform a few single-qubit gates. They are client-friendly and flexible since the clients can achieve BQC depending on their own quantum devices and resist both insider outsider attacks in quantum networks. Furthermore, all the three proposed protocols are verifiable, namely that the clients can verify the correctness of their calculations.
