1206.0849 (Riccardo Messina et al.)

Unitary transfer of entanglement in multipartite two-level systems    [PDF]

Riccardo Messina, Anna Napoli, Antonino Messina
The dynamics of a system composed by two pairs of dipolarly coupled two-level atoms is exactly studied. We show that the initial entanglement stored in a couple of atoms not directly interacting is fully transferred to the other pair in a periodic way. The observability of this phenomenon in laboratory is briefly discussed both in terms of its temporal scale and of its stability against uncertainties in the geometrical parameters defining the physical system.
