我们测量由于自发光子散射而导致的空间分离原子叠加的退相干。我们观察到随着散射光子数量的增加，退相干与分离的质变，并定量验证多光子极限下的退相干速率常数。我们的结果说明了退相干的演变与为广泛的退相干现象开发的一般模型一致。
We measure the decoherence of a spatially separated atomic superposition due to spontaneous photon scattering. We observe a qualitative change in decoherence versus separation as the number of scattered photons increases, and verify quantitatively the decoherence rate constant in the many-photon limit. Our results illustrate an evolution of decoherence consistent with general models developed for a broad class of decoherence phenomena.
