| Description | While bipartite entanglement is relatively well understood multipartite entangled states remains a mystery. In this paper, we propose a new entanglement distillation procedure for multipartite states. Our motivation lies in informatics where CAT states can be used for multipartite protocols. Presented procedure can be used to distil these CAT states from other, less entangled states. It can also be used as a tool to estimate amount of entanglement in a given state. Our procedure is based on error correction codes. As far as we known no such procedure was considered before. |
