论文摘要
我们将缓解量子误差技术应用于各种基准问题和量子计算机,以评估实践中量子误差的性能。为此,我们定义了一种以经验动机的,资源分析的误差缓解措施的指标,我们称之为改进因子,并为我们执行的每个实验计算此指标。我们执行的实验包括零噪声外推和概率误差取消,应用于在IBM,IONQ和RIGETTI量子计算机上运行的两个基准问题,以及嘈杂的量子计算机模拟器。我们的结果表明,缓解错误的平均比没有错误缓解措施更有益 - 即使在使用的其他资源归一化时,也要强调量子错误缓解的性能取决于基础计算机。
We apply quantum error mitigation techniques to a variety of benchmark problems and quantum computers to evaluate the performance of quantum error mitigation in practice. To do so, we define an empirically motivated, resource-normalized metric of the improvement of error mitigation which we call the improvement factor, and calculate this metric for each experiment we perform. The experiments we perform consist of zero-noise extrapolation and probabilistic error cancellation applied to two benchmark problems run on IBM, IonQ, and Rigetti quantum computers, as well as noisy quantum computer simulators. Our results show that error mitigation is on average more beneficial than no error mitigation - even when normalized by the additional resources used - but also emphasize that the performance of quantum error mitigation depends on the underlying computer.
