    "abstract": "We analyze the optical selection rules of the microwave-assisted transitions\nin a flux qubit superconducting quantum circuit (SQC). We show that the\nparities of the states relevant to the superconducting phase in the SQC are\nwell-defined when the external magnetic flux $\\Phi_{e}=\\Phi_{0}/2$, then the\nselection rules are same as the ones for the electric-dipole transitions in\nusual atoms. When $\\Phi_{e}\\neq \\Phi_{0}/2$, the symmetry of the potential of\nthe artificial \"atom\u0027\u0027 is broken, a so-called $\\Delta$-type \"cyclic\"\nthree-level atom is formed, where one- and two-photon processes can coexist. We\nstudy how the population of these three states can be selectively transferred\nby adiabatically controlling the electromagnetic field pulses. Different from\n$\\Lambda$-type atoms, the adiabatic population transfer in our three-level\n$\\Delta$-atom can be controlled not only by the amplitudes but also by the\nphases of the pulses.",
