| Abstract: | We propose a scheme for generating a hyperentangled four-photon cluster state that is simultaneously entangled in polarization modes and spatial modes. This scheme is based on linear optical elements, weak cross-Kerr nonlinearity, and homodyne detection. Therefore, it is feasible with current experimental technology. |
| Keywords: | hyperentangled cluster state cross-Kerr nonlinearity homodyne detection controlled-Z gate |
