Generalizes channel-state duality to algebras with centers, establishing a link between state non-separability and channel isometry, plus extension to infinite-dimensional trace-class operators.
Bianchi and Donà's proof of the von Neumann entropy variance formula uses the same subsequent calculations as the earlier proof in reference [3].
