Cavity-field induced transparency with Rydberg atoms

01/02/2018 to 30/01/2021

We propose to study experimentally and theoretically a novel concept for coherent and dissipative interactions of quantum light fields with atomic media: the cavity-field induced transparency (CIT). This phenomenon is related to electromagnetically induced transparency (EIT), but with the important difference that the classical control field of EIT is replaced by quantized fields. The control field is in the case of CIT the field mode of a microwave cavity. 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.
