Hyperentangled Bell-state analysis (HBSA) is critical for high-capacityquantum communication. Here we design two effective schemes for error-heraldeddeterministic generation and self-assisted complete analysis of hyperentangledBell states for two-photon systems in both the polarization and spatial-modedegrees of freedom, assisted by single-sided quantum-dot-cavity systems. Weconstruct an error-heralded block with a singly charged quantum dot inside asingle-sided optical microcavity, two circular polarization beam splitters, onehalf-wave plate, and one single-photon detector, in which the errors due toimperfect interactions between photons and quantum dot systems can be heralded.With this error-heralded block, the fidelity of our two schemes forhyperentangled Bell-state generation and complete HBSA can reach unit one. Whatinteresting is that by using the measured spatial-mode state to assist theanalysis of the polarization state, our complete HBSA scheme works in aself-assisted way, which greatly simplifies the analysis process and largelyrelaxes the requirements on nonlinearities. These advantages make our schemesmuch easier to implement experimentally, and have more practical applicationsin long-distance high-capacity quantum communication.
