Geometry and topology of CC and CQ states

Presenter: Michal Oszmaniec (CFT PAS)

Co-authors: Adam Sawicki (CFT PAS), Piotr Suwara (MIM UW)


In the presented work 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-Poincar\'{e} characteristics on the topological side and by the existence of symplectic and K\"{a}hler structures on the geometric side.
