A 90, 052321 (2014)2469-9934https://hdl.handle.net/10115/32503We 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.engCC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/info:eu-repo/semantics/article10.1103/PhysRevA.90.052321info:eu-repo/semantics/openAccess
