A fundamental challenge for quantum optics is the realization of nonlinear systems capable of mediating strong interactions between light fields at the few- photon level. A promising avenue to achieve this goal is the combination of cavity Quantum Electrodynamics (cQED) and Electromagnetically Induced Transparency (EIT). Along these lines, a breakthrough has been achieved recently, as a new generation of experiments has reached the necessary conditions to observe EIT with single atoms [1]. Here we study this new phenomenon theoretically and explore possible realistic applications based upon the non-classical behaviour of the system, ranging from the coherent control of the photon statistics of incident beams, to its use as a photonic gate for quantum information purposes [2]. We will highlight future perspectives and possible strategies to implement these ideas with existing cQED setups.
