    "abstract": "Cavity quantum electrodynamic (QED) is studied for two strongly-coupled\ncharge qubits interacting with a single-mode quantized field, which is provided\nby a on-chip transmission line resonator. We analyze the dressed state\nstructure of this superconducting circuit QED system and the selection rules of\nelectromagnetic-induced transitions between any two of these dressed states.\nIts macroscopic quantum criticality, in the form of ground state level\ncrossing, is also analyzed, resulting from competition between the Ising-type\ninter-qubit coupling and the controllable on-site potentials.",
