In this article, an experimental scheme of quantum Fredkin gate is proposed. This scheme is based on the cross-Kerr effect between the photons and the ancillary coherent state. Only one coherent state is required, while the single photon detector and the coincidence measurement are not required, so this Fredkin gate is scalable. In addition, this is a nearly deterministic gate with the success probability 1/133, and it is feasible with the current experimental technology in optics.
