Quatum information transfer using superconducting qubits

The aim of this paper is proposing an efficient scheme for quantum information transfer between two qubits. To reach the purpose, we consider two highly coupled detuned superconducting qubits and resonators connected by a gap-tunable qubit. By implementing an external field, superconducting central qubit can be used as a coupler to switch on/off the coupling between the initially non-interacting qubits and resonators. It is established that, the quantum information transfer between the two qubits can be appropriately achieved via our proposal.
