Universal nonlinear entanglement witnesses
arXiv:1003.0210 · doi:10.1103/PhysRevA.81.062318
Abstract
We give a universal recipe for constructing nonlinear entanglement witnesses able to detect non-classical correlations in arbitrary systems of distinguishable and/or identical particles for an arbitrary number of constituents. The constructed witnesses are expressed in terms of expectation values of observables. As such they are, at least in principle, measurable in experiments
