Abstract
The variety of multi-partite entangled states enables numerous applications in novel quantum information tasks. In order to compare the suitability of different states from a theoretical point of view classifications have been introduced. Accordingly, here we derive criteria and demonstrate how to experimentally discriminate an observed state against the ones of certain other classes of multi-partite entangled states. Our method, originating in Bell inequalities, adds an important tool for the characterization of multi-party entanglement.
