Entanglement of formation
The entanglement of formation is an entanglement measure for bipartite ... mixed states is called a convex roof construction. Entanglement of formation quantifies how many bell state s are needed per ... which pure state. Until recently, it was not known if entanglement of formation was equal to the entanglement cost . It was shown ...
