We present an efficient scheme for the complete analysis of hyperentangledGreenberger-Horne-Zeilinger (GHZ) state in polarization and time-bin degrees offreedom with two steps. First, the polarization GHZ state is distinguishedcompletely and nondestructively, resorting to the controlled phase flip (CPF)gate constructed by the cavity-assisted interaction. Subsequently, the time-binGHZ state is analyzed by using the preserved polarization entanglement. Withthe help of CPF gate and self-assisted mechanism, our scheme can be directlygeneralized to the complete N-photon hyperentangled GHZ state analysis, and itmay have potential applications in the hyperentanglement-based quantumcommunication.
