标题： Randomized benchmarking with non-Markovian noise and realistic finite-time gates

摘要： 我们分析了非马尔可夫经典噪声对单量子比特随机基准测试实验的影响，这种方法明确地通过现实的有限持续时间脉冲来模拟每个门的操作。 我们的新框架利用每个门序列的随机性，推导出完整的存活概率衰减曲线表达式，这些表达式在噪声强度上是非微扰的。 在存在非马尔可夫噪声的情况下，我们的方法表明，衰减曲线可能对实现方法有很强的依赖性，表现出指数衰减和幂律衰减的区域。 我们讨论了这些效应如何使随机基准测试实验的解释变得复杂，但也如何利用它们来探测非马尔可夫性。 显示英文摘要

摘要： We analyze the impact of non-Markovian classical noise on single-qubit randomized benchmarking experiments, in a manner that explicitly models the realization of each gate via realistic finite-duration pulses. Our new framework exploits the random nature of each gate sequence to derive expressions for the full survival probability decay curve which are non-perturbative in the noise strength. In the presence of non-Markovian noise, our approach shows that the decay curve can exhibit a strong dependence on the implementation method, with regimes of both exponential and power law decays. We discuss how these effects can complicate the interpretation of a randomized-benchmarking experiment, but also how to leverage them to probe non-Markovianty.
