    "abstract": "The four Bell-type entangled coherent states, |\\alpha\u003e|-\\alpha\u003e \\pm |-\\alpha\u003e\n|\\alpha\u003e and |\\alpha\u003e|\\alpha\u003e \\pm |-\\alpha\u003e |-\\alpha\u003e, can be discriminated\nwith a high probability using only linear optical means, as long as |\\alpha| is\nnot too small. Based on this observation, we propose a simple scheme to almost\ncompletely teleport a superposed coherent state. The nonunitary transformation,\nthat is required to complete the teleportation, can be achieved by embedding\nthe receiver\u0027s field state in a larger Hilbert space consisting of the field\nand a single atom and performing a unitary transformation on this Hilbert\nspace.",
