A Hierarchy of Entanglement    [PDF]

Federico Levi, Florian Mintert

We derive a hierarchy of separability criteria that identify the different degrees of entanglement ranging from two-body to genuine many-body entanglement in mixed quantum states. With this hierarchy we demonstrate the different dynamical behavior of various degrees of entanglement under incoherent dynamics.
