In circuit QED, a superconducting charge qubit is fabricated inside a high-quality factor transmission line resonator [1]. This opens the possibility to probe the regime of strong coupling of cavity QED using microwave photons and artificial atoms. This physics was experimentally investigated in the resonant [2] and in the dispersive [3] regime. In this talk, we will show how this setup could be used to generate single microwave photons on demand. Moreover, by using a different circuit QED layout with two resonators, photon generation could be tagged. The possibility to use a similar setup to detect single photons will also be discussed.
