Rotationally Invariant Multipartite States
Dariusz Chruściński, Andrzej Kossakowski · Open Systems & Information Dynamics · 2007
We construct a class of multipartite states possessing rotational SO (3) symmetry — these are states of K spin-jA particles and K spin-jB particles. The construction of symmetric states follows our two recent papers devoted to unitary and orthogonal multipartite symmetry. We study basic properties of multipartite SO (3) symmetric states: separability criteria and multi-PPT conditions.
