Abstract

A scheme is proposed for achieving robust population inversion in five-level systems by means of composite pulses. An example of such a system consists of the magnetic sublevels with angular momenta $J_{g} = 2$ and $J_{e} = 2$ . Through elaborately constructing the relative phases of pulse pairs, the composite sequences perform well in suppressing the uncorrelated pulse area errors. In particular, the five pulse-pair sequence possesses good robustness and a short evolution time. The composite sequences are further designed to compensate for a single type of pulse area errors to any desired order. This work provides a high-efficiency way for robust quantum state manipulation in five-level systems.

用五级系统中的复合脉冲操纵鲁棒量子态

本文提出了一种通过复合脉冲在五电平系统中实现稳健群体反转的方案。这种系统的一个例子是角矩为和的磁子级。通过精心构建脉冲对的相对相位，复合序列能很好地抑制不相关的脉冲区域误差。其中，五脉冲对序列具有良好的鲁棒性和较短的演化时间。复合序列的进一步设计可以补偿单一类型的脉冲区域误差，达到任何所需的阶次。这项工作为五级系统中的鲁棒量子态操纵提供了一种高效方法。
