    "abstract": "We suggest an entanglement purification scheme for mixed entangled coherent\nstates using 50-50 beam splitters and photodetectors. This scheme is directly\napplicable for mixed entangled coherent states of the Werner type, and can be\nuseful for general mixed states using additional nonlinear interactions. We\napply our scheme to entangled coherent states decohered in a vacuum environment\nand find the decay time until which they can be purified.",
