Abstract
We propose a scheme for the generation of hyperentangled multiqubit cluster states and Greenberger–Horne–Zeilinger states in both polarization and spatial mode degrees of freedom using the quantum-dot cavity system. This device can be used as the complete analyzer of hyperentangled multiphoton states. This proposed hyperentanglement generation and analyzer device can serve as a crucial component of high capacity, long-distance quantum communication. Using existing experimental data, it is demonstrated that the present scheme may be feasible in strong-coupling regimes with current techniques.
