TLDR
In this paper, an alternative scheme is proposed for teleportation of an unknown atomic state and an entanglement of zero-and one-photon states, based on the resonant interaction of a two-mode cavity field with a ∧-type three-level atom.Abstract:
An alternative scheme is proposed for teleportation of an unknown atomic state and an entanglement of zero- and one-photon states. The scheme is based on the resonant interaction of a two-mode cavity field with a ∧-type three-level atom. In contrast with the previously proposed schemes, the present scheme is ascendant, since the fidelity is 1.0 in principle similarly without the Bell-state measurement. And the scheme is experimentally feasible based on the current cavity QED technique.read more

Approximate conditional teleportation of a $$\varLambda $$-type three-level atomic state based on cavity QED method beyond Bell-state measurement
TL;DR: It is shown that if the atomic detection results a particular state of atom 1, an unknown state can be appropriately teleported from atom 1 to atom 2 and this teleportation procedure successfully leads to the high fidelity F in between.

Superposition of coherent states prepared in one mode of a dissipative bimodal cavity
TL;DR: In this paper, the fidelity of a superposition of coherent states engineered in a bimodal high-Q cavity was investigated and it was shown that the engineered superposition retains coherence for large times when the mean photon number of the prepared mode is of the order of unity.
