    "abstract": "In this paper, we calculate the entanglement-assisted classical information\ncapacity of amplitude damping channel and compare it with the particular mutual\ninformation which is considered as the entanglement-assisted classical\ninformation capacity of this channel in Ref. 6. It is shown that the difference\nbetween them is very small. In addition, we point out that using partial\nsymmetry and concavity of mutual information derived from dense coding scheme\none can simplify the calculation of entanglement-assisted classical information\ncapacities for non-unitary-covariant quantum noisy channels.",
