Probing Genuine Multipartite Entanglement in Large Systems
Lucas B. Vieira, Diego L. Braga Ferreira, Thiago O. Maciel +1
We introduce a new kind of Entanglement Witness which is appropriate for studying genuine multipartite entanglement in large systems. The witness operator has a form that fits natu…
