Abstract
We propose a theoretical scheme to couple superconducting charge qubits (SCQs) via Raman transitions in a circuit QED architecture. Qubit array interacts a quantum data bus generated by a one-dimensional superconducting transmission line resonator (TLR). Based on the Raman transitions, the controllable and selective interqubit couplings mediated by the data bus can be obtained by just addressing the applied gate pulses, which provides the possibility for scaling up to many SCQs.
