Abstract

A theoretical scheme is proposed to transfer quantum state with a two-dimensional Cooper-pair box qubit array in circuit QED devices, in which coplanar transmission line resonators play the role of a quantum data bus. Based on the Raman transitions, the resonator-assisted quantum state transfer between any selected pair of qubits can be performed by addressing the local gate pulses. Thus the scheme may offer an effective route towards scalable quantum state transfer with superconducting qubits.
