论文摘要
量子性测试是一种协议，经典用户对量子设备发出挑战，以确定在某些加密假设下是否表现出非古典行为。最近对当前量子计算机实施此类测试的尝试依赖于有效验证的交互式挑战，或者以低效（指数时间）验证的非交互挑战。在本文中，我们在离子陷阱量子计算机上执行了有效的量子性非相互作用测试。我们的结果大大超过了经典设备成功的界限。
A test of quantumness is a protocol where a classical user issues challenges to a quantum device to determine if it exhibits non-classical behavior, under certain cryptographic assumptions. Recent attempts to implement such tests on current quantum computers rely on either interactive challenges with efficient verification, or non-interactive challenges with inefficient (exponential time) verification. In this paper, we execute an efficient non-interactive test of quantumness on an ion-trap quantum computer. Our results significantly exceed the bound for a classical device's success.
