Multipartite invariant states. I. Unitary symmetry
- Institute of Physics, Nicolaus Copernicus University, GrudziaPdzka 5/7, 87-100 Torun (Poland)
We propose a natural generalization of bipartite Werner and isotropic states to multipartite systems consisting of an arbitrary even number of d-dimensional subsystems (qudits). These generalized states are invariant under the action of local unitary operations. We study basic properties of multipartite invariant states and present necessary and sufficient separability criteria.
