主　　题：hyperentangled Bell states analysis multiple degrees of freedom time interval 

摘      要：Hyperentangled Bell states analysis(HBSA)is an essential building block for certain hyper-parallel quantum information *** propose a complete and deterministic HBSA scheme encoded in spatial and polarization degrees of freedom(DOFs)of two-photon system assisted by a fixed frequency-based entanglement and a time interval *** parity information the spatial-based and polarization-based hyper-entanglement can be distinguished by the distinct time intervals of the photon pairs,and the phase information can be distinguished by the detection *** with previous schemes,the number of the auxiliary entanglements is reduced from two to one by introducing time interval ***,the additional frequency and time interval DOFs suffer less from the collective channel noise.
