论文摘要
我们描述了一个有效且可扩展的框架，用于建模串扰对量子信息处理器的影响。通过应用最佳控制技术，我们将展示如何在具有大量局部和非局部串扰的系统上调整任意高保真并行操作。模拟显示的2D平方阵列的错误率较大，为100个超导式矩形Qub。这些结果表明，与其努力在制造过程中努力消除不良的相互作用，我们可以通过仔细的表征和控制优化来在很大程度上减轻它们的效果。
We describe an efficient and scalable framework for modeling crosstalk effects on quantum information processors. By applying optimal control techniques, we show how to tuneup arbitrary high-fidelity parallel operations on systems with substantial local and nonlocal crosstalk. Simulations show drastically lower error rates for 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 their effects through careful characterization and control optimization.
