我们描述了一个有效的和可扩展的框架，用于模拟量子信息处理器上的串扰效应。通过应用最优控制技术，我们展示了如何调整任意高保真并行操作系统大量的本地和非本地串扰。作为一个例子，我们模拟了一个二维正方形阵列的100个超导transmon量子比特。这些结果表明，我们可以通过仔细的表征和控制优化，用软件在很大程度上减轻这种影响，而不是努力在制造过程中消除不必要的相互作用。
We describe an efficient and scalable framework for modeling crosstalk effects on quantum information processors. By applying optimal control techniques, we show how to tune-up arbitrary high-fidelity parallel operations on systems with substantial local and nonlocal crosstalk. As an example, we simulate a 2D square array of 100 superconducting transmon qubits. These results suggest that rather than striving to engineer away undesirable interactions during fabrication, we can largely mitigate such effects with software through careful characterization and control optimization.
