We prove that every unitary acting on any multipartite system and having operator Schmidt rank equal to 2 can be diagonalized by local unitaries. This then implies that every such…

Conditions for uniqueness of product representations for separable quantum channels and separable quantum states
Scott M. Cohen
We give a sufficient condition that an operator sum representation of a separable quantum channel in terms of product operators is the unique product representation for that channe…
