    "abstract": "We simplify some conjectures in quantum information theory; the additivity of\nminimal output entropy, the multiplicativity of maximal output p-norm and the\nsuperadditivity of convex closure of output entropy. We construct a unital\nchannel for a given channel so that they share the above additivity properties;\nwe can reduce the conjectures for all channels to those for unital channels.",
