Abstract
Additivity of the minimal output entropy for the family of transpose depolarizing channels introduced by Fannes et al. [quant-ph/0410195] is considered. It is shown that using the method of our previous paper [quant-ph/0403072] allows us to prove the additivity for the range of the parameter values for which the problem was left open in [quant-ph/0410195]. Together with the result of [quant-ph/0410195], this covers the whole family of transpose depolarizing channels.
