摘　　要：We propose a scheme for error-detected generation of an AT-photon cluster state with a quantum dot(QD)embedded in a single-sided optical niicrocavity(QD-cavity system).The basic structure of this scheme is an error-detected controlled-phase(C-phase)gate on the hybrid electron-photon system.In this scheme,the fidelity of N-photon cluster state generation can be reached imity even if low-Q cavity and cavity leakage are considered.By using error detecting,the generation of an AT-photon cluster state can be performed by repeating until success,which also leads to a high success probability,compared with other schemes assisted by the QD-cavity system.The error-detected generation of an N-photon cluster state in the highly controllable way may benefit on the quantum network in the future.
