Graph-associated entanglement cost of a multipartite state in exact and finite-block-length approximate constructions
Graph-associated entanglement cost of a multipartite state in exact and finite-block-length approximate constructions
We introduce and analyze graph-associated entanglement cost, a generalization of the entanglement cost of quantum states to multipartite settings. We identify a necessary and sufficient condition for any multipartite entangled state to be constructible when quantum communication between the multiple parties is restricted to a quantum network represented by a …
