Delayed (sudden) birth of entanglement
Z. Ficek, R. Tanas
The concept of time delayed creation of entanglement by the dissipative process of spontaneous emission is investigated. A threshold effect for the creation of entanglement is foun…
Dark periods and revivals of entanglement in a two qubit system
Z. Ficek, R. Tanas
In a recent paper Yu and Eberly [Phys. Rev. Lett. {\bf 93}, 140404 (2004)] have shown that two initially entangled and afterwards not interacting qubits can become completely disen…
Teleportation with insurance of an entangled atomic state via cavity decay
Grzegorz Chimczak, Ryszard Tanas, Adam Miranowicz
We propose a scheme to teleport an entangled state of two -type three-level atoms via photons. The teleportation protocol involves the local redundant encoding protecting the in…
Stationary two-atom entanglement induced by nonclassical two-photon correlations
R. Tanas, Z. Ficek
A system of two two-level atoms interacting with a squeezed vacuum field can exhibit stationary entanglement associated with nonclassical two-photon correlations characteristic of…
Entangling two atoms via spontaneous emission
R Tanas, Z. Ficek
We discuss the creation of entanglement between two two-level atoms in the dissipative process of spontaneous emission. It is shown that spontaneous emission can lead to a transien…
Entanglement induced by spontaneous emission in spatially extended two-atom systems
Z. Ficek, R. Tanas
We investigate the role of the collective antisymmetric state in entanglement creation by spontaneous emission in a system of two non-overlapping two-level atoms. We calculate and…
