    "abstract": "The quantum capacity of thermal noise channel is studied. The extremal input\nstate is obtained at the postulation that the coherent information is convex or\nconcave at its vicinity. When the input energy tends to infinitive, it is\nverified by perturbation theory that the coherent information reaches its\nmaximum at the product of identical thermal state input. The quantum capacity\nis obtained for lower noise channel and it is equal the one shot capacity.",
