We propose a scheme for generating four-photon polarization-entangled cluster states based on the cross-Kerr nonlinear interaction between field-modes. Compared with other schemes, our scheme introduces the idea of parity gate and uses the non-destructive measurement method based on homodyne detection, which is easier to implement in experiment.
