- Abstract
The familiar Greenberger–Horne–Zeilinger (GHZ) states can be rewritten
by entangling the Bell states for two qubits with a third qubit state,
which is dubbed entangled entanglement. We show that in a
constructive way we obtain all eight independent GHZ states that form
the simplex of entangled entanglement, the magic simplex. The
construction procedure allows a generalization to higher dimensions
both, in the degrees of freedom (considering qudits) as well as in the
number of particles (considering n-partite states). Such bases of GHZ-type states exhibit a cyclic geometry, a Merry Go Round, that is relevant for experimental and quantum information theoretic applications.
