We present a way to realize quantum information transfer with superconducting flux qubits coupled to a cavity. Because only resonant qubit–cavity and qubit–pulse interactions are applied, the information transfer can be performed much faster when compared with the previous proposals. This proposal does not require adjustment of the qubit level spacings during the operation. Moreover, neither uniformity in the device parameters nor exact placement of qubits in the cavity are needed.
