On the Description of Bistochastic Kadison-Schwarz Operators on 2(ℂ)

In this paper we describe bistochastic Kadison-Schawrz operators on M2(C). Such description allows us to ¯nd positive, but not Kadison-Schwarz operators. Moreover, by means of this characterization we can construct Kadison{Schawrz operators which are not completely positive
