3. (quantum mechanics, countable) Quantum entanglemant that occurs in theory but which seldom (or never) arises because of other physical restrictions.

     Because of this a whole different class of states called the fluffy-bunnies arises which are robust entanglements due to the measurements and interactions between particles.

     Note, however, a subtlety: in general, this inequality is strict (apart from when both sides are zero), due to a necessary reduction in entanglement after applying the dephasing operation Φ_A ⊗ Φ_B and removing the fluffy bunny entanglement.
