    "abstract": "In this paper, we first propose a general entanglement distillation protocol\nfor three-particle W class state, which can concentrate the state\n(non-maximally entangled W state). The general protocol is mainly based on the\nunitary transformations on the auxiliary particles and the entangled particles,\nand a feasible physical scheme is suggested based on the cavity QED techniques.\nThe protocol and scheme can be extended to the entanglement concentration of\nN-particle case.",
