Abstract

To date, blind quantum computing demonstrations require clients to have weak quantum devices. Here we implement a proof-of-principle experiment for completely classical clients. Via classically interacting with two quantum servers that share entanglement, the client accomplishes the task of having the number 15 factorized by servers who are denied information about the computation itself. This concealment is accompanied by a verification protocol that tests servers' honesty and correctness. Our demonstration shows the feasibility of completely classical clients and thus is a key milestone towards secure cloud quantum computing.

摘要

迄今为止，盲量子计算演示要求客户拥有弱量子设备。在此，我们为完全经典的客户实现了一个原理验证实验。通过与两个共享纠缠的量子服务器进行经典交互，客户完成了让服务器对数字15进行因式分解的任务，而服务器被剥夺了有关计算本身的信息。这种隐蔽性伴随着一个测试服务器诚实性和正确性的验证协议。我们的演示展示了完全经典客户的可行性，因此是迈向安全云量子计算的一个关键里程碑。
