The probabilistic charge transfer in tunnel junctions is a source of current noise, which can be picked up by the environment of the junction where it creates electromagnetic excitations - or photons. In this thesis, we demonstrate that a superconducting tunnel junction coupled to a tailored environment can act as a bright source of quantum microwave radiation. The energy required to create photons is extracted from a DC voltage source during the inelastic tunneling of Cooper pair through the junction. We detect this emitted light and study its properties with quantum optics tools adapted to the microwave domain. We characterize the singlephoton nature of the light emitted in a single mode strongly coupled to a junction, as well as the enta...
