Multipartite entanglement
... composed of $\; m>2$ subsystems the definition of separable and entangled states is richer than in the bipartite case. Indeed, in the multipartite case, apart from fully separable and fully entangled states, there also exists the notion of ...

Separability criteria
... Although there exists a clear definition of what separable and entangled states are, in general it is difficult to determine whether a given state is entangled or separable. Linear maps which are positive but not completely positive (PnCP) ...
