A Computable Criterion for Partial Entanglement in Continuous Variable Quantum Systems
arXiv:1101.0972 · doi:10.1103/PhysRevA.83.052318
Abstract
A general and computable criterion for k-(in)separability in continuous multipartite quantum systems is presented. The criterion can be experimentally implemented with a finite and comparatively low number of local observables. We discuss in detail how the detection quality can be optimised.
