在I2分子的B电子态，利用一对飞秒激光脉冲精确控制了两个分子波包的量子干涉，并利用另一个飞秒激光脉冲观测到了两个分子波包的实时演化。可以清楚地观察到，时间演化作为锁定脉冲之间的相对相位的函数急剧变化，使我们能够读取存储在分子系综的波函数中的振幅和相位信息。
The quantum interference of two molecular wave packets has been precisely controlled in the B electronic state of the I2 molecule by using a pair of fs laser pulses whose relative phase is locked within the attosecond time scale and its real-time evolution has been observed by another fs laser pulse. It is clearly observed that the temporal evolution changes drastically as a function of the relative phase between the locked pulses, allowing us to read both amplitude and phase information stored in the wave functions of the molecular ensemble.
