    • This follows from the definition of multipartite entanglement in a pure state: since the state is not separable with respect to any bipartition, it must be 4-partite entangled. Further work utilizing this definition to construct multipartite entanglement measures may be found in, for instance, 10.1103/PhysRevA.69.052330;

    • For example, characterizing the two-body entanglement requires calculating qubit-qubit, qubit-qutrit, and qutrit-qutrit entanglement in mixed states. Extensions to larger systems and/or more excitations would produce higher-dimensional effective systems for the field, further complicating the problem.
