我们证明了由于单个Rb原子和单个RbCs分子之间的电荷偶极相互作用而导致的Rydberg阻塞。该分子由Rb+Cs原子对的磁缔合形成，随后以91（1）%的效率转移到振转基态。物种特异性镊子用于控制原子和分子之间的分离。当原子-分子间距设置为310（40）nm时，电荷-偶极相互作用导致到Rb（52 s）里德堡态的跃迁被阻断。所观察到的激发动力学与使用计算的相互作用势的模拟结果吻合良好。我们的研究结果开辟了一个混合平台的前景，其中量子信息被转移之间的单独捕获的分子使用里德伯原子。
We demonstrate Rydberg blockade due to the charge-dipole interaction between a single Rb atom and a single RbCs molecule confined in optical tweezers. The molecule is formed by magnetoassociation of a Rb+Cs atom pair and subsequently transferred to the rovibrational ground state with an efficiency of 91(1)%. Species-specific tweezers are used to control the separation between the atom and molecule. The charge-dipole interaction causes blockade of the transition to the Rb(52s) Rydberg state, when the atom-molecule separation is set to 310(40) nm. The observed excitation dynamics are in good agreement with simulations using calculated interaction potentials. Our results open up the prospect of a hybrid platform where quantum information is transferred between individually trapped molecules using Rydberg atoms.
