Computing Stabilized Norms for Quantum Operations via the Theory of Completely Bounded Maps

Quantum Physics 2007-11-26 v1

Abstract

The diamond and completely bounded norms for linear maps play an increasingly important role in quantum information science, providing fundamental stabilized distance measures for differences of quantum operations. Based on the theory of completely bounded maps, we formulate an algorithm to compute the norm of an arbitrary linear map. We present an implementation of the algorithm via Maple, discuss its efficiency, and consider the case of differences of unitary maps.
