Spatial decoherence factor via the qubit-field interaction
A. Vaglica, G. Vetri
We analyze the time evolution of an initial spatial coherence for a two level atom whose internal degrees of freedom interact with a single mode of a cavity field. When the qubit-f…
Irreversible decay of nonlocal entanglement via a reservoir of a single degree of freedom
A. Vaglica, G. Vetri
Recently, it has been realized that nonlocal disentanglement may take a finite time as opposite to the asymptotic decay of local coherences. We find in this paper that a sudden irr…
On the observability of Bell's inequality violation in the optical Stern-Gerlach model
M. Tumminello, A. Vaglica, G. Vetri
Using the optical Stern-Gerlach model, we have recently shown that the non-local correlations between the internal variables of two atoms that successively interact with the field…
Quantum erasure within the Optical Stern-Gerlach Model
M. Chianello, M. Tumminello, A. Vaglica +1
In the optical Stern-Gerlach effect the two branches in which the incoming atomic packet splits up can display interference pattern outside the cavity when a field measurement is m…
Translational dynamics effects on the non-local correlations between two atoms
M. Tumminello, A. Vaglica, G. Vetri
A pair of atoms interacting successively with the field of the same cavity and exchanging a single photon, leave the cavity in an entangled state of Einstein-Podolsky-Rosen (EPR) t…
The non dissipative damping of the Rabi oscillations as a "which-path" information
M. Tumminello, A. Vaglica, G. Vetri
Rabi oscillations may be viewed as an interference phenomenon due to a coherent superposition of different quantum paths, like in the Young's two-slit experiment. The inclusion of…
