论文摘要
模拟量子模拟预计将是近期量子设备的重要应用。在没有比较已知仿真结果的情况下，对这些设备进行验证将是一项重要任务，因为系统大小超出了可以经典模拟的制度。我们为模拟量子模拟器引入了一组实验动机的验证方案，讨论了它们对各种误差源的敏感性及其对较大系统大小的可扩展性。我们使用两个Quibt的捕获模拟量子模拟器在实验上证明了这些协议，并使用多达五个Qubit的模型进行数值。
Analog quantum simulation is expected to be a significant application of near-term quantum devices. Verification of these devices without comparison to known simulation results will be an important task as the system size grows beyond the regime that can be simulated classically. We introduce a set of experimentally-motivated verification protocols for analog quantum simulators, discussing their sensitivity to a variety of error sources and their scalability to larger system sizes. We demonstrate these protocols experimentally using a two-qubit trapped-ion analog quantum simulator and numerically using models of up to five qubits.
