论文摘要
We present an efficient scheme for the complete analysis of hyperentangled Greenberger-Horne-Zeilinger (GHZ) state in polarization and time-bin degrees of freedom with two steps.首先，极化GHz状态被完全和非损坏区分开，诉诸于由腔体辅助相互作用构建的受控相位翻转（CPF）门。随后，通过使用保留的极化纠缠来分析时态GHz状态。借助CPF门和自辅助机制，我们的方案可以直接概括为完整的N-Photon超牢房GHz状态分析，并且它可能在基于超伦敦的量子通信中具有潜在的应用。
We present an efficient scheme for the complete analysis of hyperentangled Greenberger-Horne-Zeilinger (GHZ) state in polarization and time-bin degrees of freedom with two steps. First, the polarization GHZ state is distinguished completely and nondestructively, resorting to the controlled phase flip (CPF) gate constructed by the cavity-assisted interaction. Subsequently, the time-bin GHZ state is analyzed by using the preserved polarization entanglement. With the help of CPF gate and self-assisted mechanism, our scheme can be directly generalized to the complete N-photon hyperentangled GHZ state analysis, and it may have potential applications in the hyperentanglement-based quantum communication.
