Light-matter interaction described with a fully quantized model provides the possibility of utilizing quantum correlations of light [1]. Especially the excitation of materials by nonclassical light can lead to new effects and applications [2] that can be of special interest for quantum metrology and quantum communication.
Our investigations were performed using a Jaynes-Cummings-like model with three electronic levels and two light states, where coherent and squeezed states were considered. Our system contains different loss mechanisms, namely, dephasing, cavity and radiative losses.
The energy level population dynamic was calculated, this dynamic is a unique signature, determined by the photon statistics. Electromagnetically induced transparency (EIT) is demonstrated with quantized light. Special features of the EIT regime were found in the case of excitation by squeezed light. Moreover, quantum correlations between fields were studied.
