摘要：
We theoretically study the system of a superconducting transmission line resonator coupled to two interacting superconducting flux qubits.It is shown that under certain conditions the resonator mode can be tuned to two-photon resonance between the ground state and the highest excited state while the middle excited states are far-off resonance.Furthermore,we study the steady-state properties of the flux qubits and resonator,such as the photon statistics,the spectrum and squeezing of the resonator,and demonstrate that two-photon laser can be implemented with current experimental technology.
