Measure of genuine multipartite entanglement with computable lower bounds
arXiv:1101.2001 · doi:10.1103/PhysRevA.83.062325
Abstract
We introduce an intuitive measure of genuine multipartite entanglement which is based on the well-known concurrence. We show how lower bounds on this measure can be derived that also meet important characteristics of an entanglement measure. These lower bounds are experimentally implementable in a feasible way enabling quantification of multipartite entanglement in a broad variety of cases.
