Contrary to natural atoms, artificial atoms are always coupled to a solid-state environment, e.g. wandering carriers or phononic vibrations of the matrix they are embedded in. Because of the decoherence it induces, this environment has historically played the role of the villain, that alters the potential of the emitter for quantum information purposes. I will review theoretical proposals and recent experimental developments showing that cavity QED can be used to exploit such decoherence, to develop advanced photonic devices operating at finite temperature.
