Abstract: 
The last two decades have seen tremendous advances in our ability to generate and manipulate quantum coherence in mesoscopic superconducting circuits. These advances have opened up the study of quantum optics of microwave photons in superconducting circuits as well as providing important hardware for the manipulation of quantum information. Focusing primarily on charge-based qubits, we provide a brief overview of these developments  and discuss the present state of the art. We also survey the remarkable progress that has been made in realizing circuit QED in which superconducting artificial atoms are strongly coupled to individual microwave photons.
