Complete analysis of hyperentangled Bell state in three degrees of freedom

Abstract

We present an efficient scheme for the complete hyperentangled Bell state analysis (HBSA) of photon system in polarization and two longitudinal momentum degrees of freedom (DOFs). In the process of distinguishing the 64 hyperentangled Bell states in three DOFs, the weak cross-Kerr nonlinearity and self-assisted mechanism are both utilized, which can make our scheme simple and realizable. We also discuss the application of this complete HBSA scheme in quantum teleportation that based on hyperentangled state in three DOFs
