Transferring quantum entangled states between multiple single-photon-state qubits and coherent-state qubits in circuit QED

Qi-Ping Su, Hanyu Zhang, Chui-Ping Yang

We present a way to transfer maximally- or partially-entangled states of n single-photon-state (SPS) qubits onto n coherent-state (CS) qubits, by employing 2n microwave cavities co…
