Genuine Entanglement in Complex Systems

Abstract:

We present a general framework to construct criteria detecting genuinely multipartite entangled mixed quantum states in arbitrary-dimensional systems. We show that the resulting versatile set of criteria enables entanglement detection in systems, that had been unaccessible so far. They are experimentally implementable using local measurements without quantum state tomography and scale very favorably with system size. We then show how such a framework might be used to reveal even more about the structure of multipartite entanglement, e.g. detection of non k-separability and even possible classification)
