Kraus theorem

WebLet $\Phi$ be a linear and completely positive map on $\frak T(\mathcal H)$ where $\mathcal H$ is a separable Hilbert space. Then its dual map $\Phi^*$ acting on $\mathcal B(\mathcal H)$ is linear and completely positive (the equivalence of complete positivity of $\Phi$ and $\Phi^*$ is well known) and the duality relation implies that $\Phi^*$ is … WebRobust Schur polynomial stability and Kharitonov's theorem.

In the context of quantum information theory, the operators {Vi} are called the Kraus operators (after Karl Kraus) of Φ. Notice, given a completely positive Φ, its Kraus operators need not be unique. For example, any "square root" factorization of the Choi matrix CΦ = B B gives a set of Kraus operators. Let Webwith Kraus operators that satisfy a completeness relation can be realized by a measurement model. The converse is stated formally as the Kraus representation theorem.
