我们用单个激光脉冲演示了原子的两个超精细基态之间的亚皮秒时间尺度布居转移。我们的方案利用在Rabi振荡过程中通过精细结构激发态产生的几何和动力学相来构造超精细态量子比特系统的$X$旋转门。用飞秒激光和冷原子在磁光囚禁中进行的实验表明，时钟态之间的最大布居转移超过98%。
We demonstrate subpicosecond-time-scale population transfer between the pair of hyperfine ground states of atomic rubidium using a single laser-pulse. Our scheme utilizes the geometric and dynamic phases induced during Rabi oscillation through the fine-structure excited state in order to construct an $X$ rotation gate for the hyperfine-state qubit system. Experiment performed with a femtosecond laser and cold rubidium atoms, in a magneto-optical trap, shows over 98\% maximal population transfer between the clock states.
