%X A linear optical experimental scheme for generation of spatial entangled qudits is proposed, which is based on the post-selection technique and is realized with some certain probability. In order to do it deterministically, the scheme based on the C-path gate which works with weak cross-Kerr nonlinearity is proposed. This new scheme is suitable for the generation of spatial entangled qudits with any photons and any dimensions. Since the generation is deterministic without post-selection technique, the entangled qudits can be used in the quantum information process without any limits. In addition, this scheme is feasible for current experimental technology.
