Abstract

We propose a scheme to implement quantum state transfer in a hybrid circuit quantum electrodynamics (QED) system which consists of a superconducting charge qubit, a flux qubit, and a transmission line resonator (TLR). It is shown that quantum state transfer between the charge qubit and the flux qubit can be realized by using the TLR as the data bus.
