Coexistence of single- and multi-photon processes due to longitudinal couplings between superconducting flux qubits and external fields
In contrast to natural atoms, the potential energies for superconducting flux qubit (SFQ) circuits can be artificially controlled. When the inversion symmetry of the potential energy is broken, we find that multi-photon processes can coexist in multi-level SFQ circuits. Moreover, there are not only...
