Bell-state analysis (BSA) is essential in quantum communication, but it isimpossible to distinguish unambiguously the four Bell states in thepolarization degree of freedom (DOF) of two-photon systems with only linearoptical elements, except for the case in which the BSA is assisted withhyperentangled states, the simultaneous entanglement in more than one DOF.Here, we propose a scheme to distinguish completely the 16 hyperentangled Bellstates in both the polarization and the spatial-mode DOFs of two-photonsystems, by using the giant nonlinear optics in quantum dot-cavity systems.This scheme can be applied to increase the channel capacity of long-distancequantum communication based on hyperentanglement, such as entanglementswapping, teleportation, and superdense coding. We use hyperentanglementswapping as an example to show the application of this HBSA.
