QUANTUM ENTANGLEMENTS AND ENTANGLED MUTUAL ENTROPY
, 2000
"... Abstract. The mathematical structure of quantum entanglement is studied and classified from the point of view of quantum compound states. We show that the classicalquantum correspondences such as encodings can be treated as diagonal (d) entanglements. The mutual entropy of the dcompound and entan ..."

compound and entangled states lead to two different types of entropies for a given quantum state: the von Neumann entropy, which is achieved as the supremum of the information over all dentanglements, and the dimensional entropy, which is achieved at the standard entanglement, the true quantum entanglement, coinciding
On Fermion Entanglement
, 2005
"... Under the historical definition of entanglement, namely that encountered in Einstein– Podolski–Rosen (EPR)–type experiments, it is shown that a particular Slater determinant is entangled. Thus a definition which holds that any Slater determinant is unentangled, found in the literature, is inconsiste ..."

Entangled Entanglement: The Geometry of GHZ States
"... The familiar GreenbergerHorneZeilinger (GHZ) states can be rewritten by entangling the Bell states for two qubits with a state of the third qubit, which is dubbed entangled entanglement. We show that in this way we obtain all 8 independent GHZ states that form the simplex of entangled entanglement ..."

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 npartite states). Such bases of GHZtype states exhibit a certain geometry that is relevant
Entanglement entropy, conformal invariance and extrinsic geometry,” Phys
 Lett. B
, 2008
"... We use the conformal invariance and the holographic correspondence to fully specify the dependence of entanglement entropy on the extrinsic geometry of the 2d surface Σ that separates two subsystems of quantum strongly coupled N = 4 SU(N) superconformal gauge theory. We extend this result and calcul ..."

and calculate entanglement entropy of a generic 4d conformal field theory. As a byproduct, we obtain a closedform expression for the entanglement entropy in flat spacetime when Σ is sphere S2 and when Σ is twodimensional cylinder.

"... A quantum telecloning process combining quantum teleportation and optimal quantum cloning from one input to M outputs is presented. The scheme relies on the establishment of particular multiparticle entangled states, which function as multiuser quantum information channels. The entanglement structu ..."
