On multipartite invariant states II. Orthogonal symmetry
arXiv:quant-ph/0601110 · doi:10.1103/PhysRevA.73.062315
Abstract
We construct a new class of multipartite states possessing orthogonal symmetry. This new class defines a convex hull of multipartite states which are invariant under the action of local unitary operations introduced in our previous paper "On multipartite invariant states I. Unitary symmetry". We study basic properties of multipartite symmetric states: separability criteria and multi-PPT conditions.
