Hierarchies of multipartite entanglement for continuous-variable states
arXiv:1409.5347 · doi:10.1103/PhysRevA.90.052321
Abstract
We derive a hierarchy of separability criteria for multi-mode continuous variable systems. They permit 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.
