原子干涉仪中从单光子退相干到多光子退相干

From Single to Multiple-Photon Decoherence in an Atom Interferometer

David A. Kokorowski, Alex D. Cronin, Tony D. Roberts, David E. Pritchard

摘要:

我们测量了空间分离原子叠加态由于自发光子散射引起的退相干。我们观察到的退相干与分离的散射光子的数量增加的定性变化,并验证定量的退相干速率常数在多光子限制。我们的研究结果说明了退相干的演变与一般模型开发了广泛的一类退相干现象。

英文摘要:

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 phenomenon.
