    "abstract": "In this paper, we propose two general entanglement distillation protocols,\nwhich can concentrate the non-maximally entangled pure W class state. The\ngeneral protocols are mainly based on the unitary transformation on the\nauxiliary particle and one of the three entangled particles, and in the second\nprotocol, the entanglement distillation includes two meanings, namely,\nextracting the concentrated tripartite entangled W state and obtaining the\nmaximally entangled bipartite state from the garbage state, which gives no\ncontribution to the distillation of non-maximally entangled pure W class state.\nWe can make use of the garbage in the distillation process, and make the\nentanglement waste in quantum communication as small as possible. A feasible\nphysical scheme is suggested based on the cavity QED.",
