在这篇文章中，我们提出了在量子信息处理器中的串扰的实验表征闲置层析成像和同步随机基准。我们量化的“量子”和“经典”的设备中的串扰和分析考虑串扰的量子电路。我们表明，只考虑门误差的模拟偏离实验结果高达<inline-formula><tex-math notation="LaTeX">27美元</tex-math></inline-formula>，而考虑门误差和串扰的模拟匹配的实验更准确的平均失配低至<inline-formula><tex-math notation="LaTeX">4.52美元</tex-math></inline-formula>。这篇文章可以用实验串扰误差率来模拟量子电路。
In this article, we present the experimental characterization of crosstalk in quantum information processor using idle tomography and simultaneous randomized benchmarking. We quantify both “quantum” and “classical” crosstalk in the device and analyze quantum circuits considering crosstalk. We show that simulation considering only gate-error deviates from experimental results up to <inline-formula><tex-math notation="LaTeX">$27\%$</tex-math></inline-formula>, whereas simulation considering both gate error and crosstalk match the experiments more accurately with an average mismatch as low as <inline-formula><tex-math notation="LaTeX">$4.52\%$</tex-math></inline-formula>. This article enables simulation of quantum circuits with experimental crosstalk error rates.
