Entanglement classes of three-qubit generalized Werner states — •Christopher Eltschka1 and Jens Siewert2,31Institut für theoretische Physik, Universität Regensburg, 93040 Regensburg, Germany — 2Departamento de Química Física, Universidad del País Vasco, 48080 Bilbao, Spain — 3Ikerbasque, Basque Foundation for Science, 48011 Bilbao, Spain

Determining the entanglement properties of multipartite states is a notoriously hard problem. Even for mixed states of three qubits, no general solution is known. An important special case are the mixtures of a maximally entangled state with white noise, also known as generalized Werner states.

We provide a complete solution giving the entanglement class not only for the generalized Werner states based on the three-qubit GHZ state, but for all states sharing the same symmetry.
