Atomic teleportation via cavity QED and position measurements: efficiency analysis
Michele Tumminello, Francesco Ciccarello
We have recently presented a novel protocol to teleport an unknown atomic state via cavity QED and position measurements. Here, after a brief review of our scheme, we provide a qua…
Teleportation of atomic states via position measurements
Michele Tumminello, Francesco Ciccarello
We present a scheme for conditionally teleporting an unknown atomic state in cavity QED, which requires two atoms and one cavity mode. The translational degrees of freedom of the a…
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…
