Abstract

Convex sets of completely positive maps and positivesemidefinite kernels are considered in a very general context of modules over Calgebras and a complete characterization of their regular extremal points is obtained As a byproduct we determine extremal autocorrelation functions We present a generalization for the Choi isomorphism widely used in quantum information theory and generalize the concept of a completely positive quantum instrument
