We propose to study experimentally and theoretically two novel concepts for coherent and dissipative interactions of quantum light fields with atomic media: cavity-field induced transparency (CIT) and dipolar-exchange induced transparency (DEIT). Both phenomena are related to electromagnetically induced transparency (EIT), but with the important difference that the classical control field of EIT is replaced by quantized fields. In the case of CIT, the control field is the field mode of a microwave cavity; in the case of DEIT, the control is the dipolar exchange field of one or more control atoms in a suitable Rydberg state. Strong coupling of the quantized fields to the atoms will be achieved by employing microwave transitions between atomic Rydberg-states. The quantized excitations of the control field make the transparency of the medium for the input probe laser photon-number selective. This will permit realization of number-state filters and transistors for optical photons, coherent conversion and dissipative state mapping between microwave and optical photons, and studies of atom-photon bound states and their interactions.

本文提出了两个量子光场与原子介质的相干和耗散相互作用的新概念：腔场诱导透明（CIT）和偶极交换诱导透明（DEIT）。这两种现象都与电磁感应透明（EIT）有关，但重要的区别是EIT的经典控制场被量子化场所取代。在CIT的情况下，控制场是微波腔的场模式;在DEIT的情况下，控制是一个或多个控制原子在合适的里德伯态的偶极交换场。量子化场与原子的强耦合将通过原子里德伯态之间的微波跃迁来实现。控制场的量子化激发使得介质对入射探测激光的透明性具有光子数选择性。这将允许实现光子的数态滤波器和晶体管，微波和光子之间的相干转换和耗散态映射，以及原子-光子束缚态及其相互作用的研究。
