Perhaps considering minimum output entropy of high tensor powers of quantum channels is one of best ways to understand capacity of quantum channels. However, if addivity violation is a local phenomena in terms of tensor powers, we may be able to obtain a simple formula for regularized minimum output entropy. In this talk, we discuss this problem with random quantum channels generated by the orthogonal group.
