论文摘要
我们提出了一个有效的方案，用于具有极化和两个纵向动量自由度（DOF）的光子系统的完整超座状钟状态分析（HBSA），诉诸弱跨kerr非线性，线性光学元件和单个光子检测器。在区分三个DOF中的64个超牢房的铃铛状态的过程中，自我辅助机制被嵌入，这使我们的方案变得简单且可实现。此外，我们已经讨论了这种完整的HBSA方案在三个DOF中基于光子超脑的高容量量子通信方案中的应用。
We present an efficient scheme for the complete hyperentangled Bell state analysis (HBSA) of photon system with polarization and two longitudinal momentum degrees of freedom (DOFs), resorting to weak cross-Kerr nonlinearity, linear optical elements and single photon detectors. In the process of distinguishing the 64 hyperentangled Bell states in three DOFs, the self-assisted mechanism is embedded, which makes our scheme simple and realizable. Moreover, we have discussed the applications of this complete HBSA scheme for high-capacity quantum communication protocols that are based on photonic hyperentanglement in three DOFs.
