Query: Selective-Resonance-Based Quantum Entangling Operation on Qubits in
  Circuit QED   We present a fast quantum entangling operation on superconducting qubits
assisted by a resonator in the quasi-dispersive regime with a new effect ---
the selective resonance coming from the amplified qubit-state-dependent
resonator transition frequency and the tunable period relation between a wanted
quantum Rabi oscillation and an unwanted one. This operation does not require
any kind of drive fields and the interaction between qubits. More interesting,
the non-computational third excitation states of the charge qubits can play an
important role in shortening largely the operation time of the entangling
gates. All those features provide an effective way to realize much faster
quantum entangling gates on superconducting qubits than previous proposals.
