On multipartite invariant states I. Unitary symmetry
Dariusz Chruscinski, Andrzej Kossakowski
abstract: 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: separability criteria and multi-PPT conditions.
