Macroscopic observables detecting genuine multipartite entanglement and partial inseparability in many-body systems
Original language description
We show a general approach for detecting genuine multipartite entanglement and partial inseparability in many-body systems by means of macroscopic observables (such as the energy) only. We show that the obtained criteria detect large areas of genuine multipartite entanglement and partial entanglement in typical mixed many-body states, which are not detected by other criteria. As genuine multipartite entanglement is a necessary property for several quantum information theoretic applications such as, e.g., secret sharing or certain kinds of quantum computation, our methods can be used to select or design appropriate condensed matter systems.
