用于量子计算的脉冲序列补偿研究进展

Progress in compensating pulse sequences for quantum computation

J. True Merrill, Kenneth R. Brown

摘要:

量子比特状态的控制经常受到系统控制误差的阻碍。补偿脉冲序列已经成为减少量子误差的一种资源有效的方法。在这篇综述中,我们讨论了补偿复合脉冲方法,并介绍了一个统一的控制理论框架,使用动态相互作用的图片。这承认一个新的几何图片序列被解释为向量路径上的动态李代数。用这种方法描述了单量子比特和多量子比特操作的序列。

英文摘要:

The control of qubit states is often impeded by systematic control errors. Compensating pulse sequences have emerged as a resource efficient method for quantum error reduction. In this review, we discuss compensating composite pulse methods, and introduce a unifying control-theoretic framework using a dynamic interaction picture. This admits a novel geometric picture where sequences are interpreted as vector paths on the dynamical Lie algebra. Sequences for single-qubit and multi-qubit operations are described with this method.
