微波场用于控制储存在高度激发的集体态（里德伯极化激元）中的光子对之间的相互作用。我们发现，强偶极-偶极相互作用引起的微波场破坏的相干性极化激元模式与一个以上的里德伯激发。因此，优先从样本中检索对应于单个存储光子的单极化子模式。对恢复光场的光子统计的测量也揭示了相互作用极化激元的非平凡传播动力学。
A microwave field is used to control the interaction between pairs of optical photons stored in highly excited collective states (Rydberg polaritons). We show that strong dipole-dipole interactions induced by the microwave field destroy the coherence of polariton modes with more than one Rydberg excitation. Consequently, single-polariton modes, which correspond to single stored photons, are preferentially retrieved from the sample. Measurements of the photon statistics of the retrieved light field also reveal nontrivial propagation dynamics of the interacting polaritons.
