    Hierarchies of multipartite entanglement for continuous-variable states
    (Physical Review A, 2014-11-14) Valido, Antonio A; Mintert, Florian; Levi, Federico
    We derive a hierarchy of separability criteria for multimode continuous-variable systems. They permit one to study in a unified way the k-partite entanglement of broad classes of Gaussian and non-Gaussian states. With specific examples we demonstrate the strength of the criteria, and we discuss their assessment based on data obtained from Gaussian measurements.
