利用Morigi等人提出的回波技术，我们在空腔量子电动力学实验中实现了原子场相互作用的时间反转。原子拉比振荡在相干场中的坍缩被逆转，从而产生诱导的复活信号。这种“回声”的振幅对非酉退相干过程很敏感。它的观测证明了在坍缩和恢复时间之间的空腔中存在场态的介观量子叠加。
Using an echo technique proposed by Morigi et al., we have time-reversed the atom-field interaction in a cavity quantum electrodynamics experiment. The collapse of the atomic Rabi oscillation in a coherent field is reversed, resulting in an induced revival signal. The amplitude of this "echo" is sensitive to nonunitary decoherence processes. Its observation demonstrates the existence of a mesoscopic quantum superposition of field states in the cavity between the collapse and the revival times.
