Maximally entangled set of tripartite qutrit states and pure state separable transformations which are not possible via local operations and classical communication
Martin Hebenstreit, Cornelia Spee, Barbara Kraus · Physical Review A · 2016
The structure of multipartite quantum states can be very complex. Here the authors analyze a pure entangled 3-qutrit system, and show that a given convertibility property is fulfilled by separable operations (SEP) but not by local operations and classical communications (LOCC), a result that was previously proved to hold true for mixed states only.
