Abstract

Convex polytopes are convex hulls of point sets in the n-dimensional space E n that generalize 2-dimensional convex polygons and 3-dimensional convex polyhedra. We concentrate on the class of n-dimensional polytopes in E n called sign permutation polytopes. We characterize sign permutation polytopes before relating their construction to constructions over the space of quantum density matrices. Finally, we consider the problem of state identication and show how sign permutation polytopes may be useful in addressing issues of robustness.
