    The Holevo-Schumacher-Westermoreland (HSW) channel capacity for the qudit unital channels was considered. A simpler formula for computing HSW channel capacity was given. And the HSW channel capacity can be determined by using only pure states. This result simplifies the computation of HSW channel capacity for the qudit unital channel.
