Quantum entanglement distributions

Question

Hi,

I'm looking literature on the subject of how to categorize a quantum ensemble of particles in terms of n-order entanglements. For example, one might want to display a given property, say number density, and see how much particles are unentangled, pair-entangled, triple-entangled, etc as an histogram which one calls entanglement density distribution and study properties or perturbations that affect that distribution.

Look up multipartite entanglement.
