Geometry and topology of CC and CQ states
/ Authors
/ Abstract
We show that mixed bipartite CC and CQ states are geometrically and topologically distinguished in the space of states. They are characterized by non-vanishing Euler-Poincare characteristics on the topological side and by the existence of symplectic structures on the geometric side.
