Quantum behaviour of a flux qubit coupled to a resonator [PDF]

, 2010
We present a detailed theoretical analysis for a system of a superconducting flux qubit coupled to a transmission line resonator. The master equation, accounting incoherent processes for a weakly populated resonator, is analytically solved.
