鲁棒和有效的原位量子控制
Robust and efficient in situ quantum control
摘要：
量子系统的精确控制是量子技术以及量子和纳米尺度物理探测的驱动力。我们提出了一种实现独立的方法，利用最新的进展直接估计的量子门保真度在原位量子控制。我们的算法考虑了问题的随机性，适合于闭环控制，并且每次迭代只需要恒定数量的保真度估计实验，与控制空间的维数无关。它对统计和技术噪声都是有效和鲁棒的。
英文摘要：
Precision control of quantum systems is the driving force for both quantum technology and the probing of physics at the quantum and nano-scale. We propose an implementation independent method for in situ quantum control that leverages recent advances in the direct estimation of quantum gate fidelity. Our algorithm takes account of the stochasticity of the problem and is suitable for closed-loop control and requires only a constant number of fidelity estimating experiments per iteration independent of the dimension of the control space. It is efficient and robust to both statistical and technical noise.
