Geometry and topology of CC and CQ states
arXiv:1305.3660 · doi:10.1063/1.4883879
Abstract
We show that multipartite mixed bipartite CC and CQ states are geometrically and topologically distinguished in the space of states. They are characterized by non-vanishing Euler-Poincaré characteristics on the topological side and by the existence of symplectic structure on the geometric side.
