Abstract

We present an experimental scheme to generate a class of entangled atomic W states useful for perfect teleportation and superdense coding. It employs three two-level (Rydberg) atoms crossing two nonresonant cavities in such a way that the first and second (the second and third) atoms are entangled via atomic collision in the first (second) cavity. The experimental realization with current technology is discussed.

Generation of an Entangled State of Two Multilevel Atoms in Cavity QED

Zhiming Zhan, Wen‐Xing Yang, Jiahua Li

We present a simple scheme to generate a maximally entangled state of two four-level Rydberg atoms with a nonresonant cavity by cavity-assisted collisions. By using this scheme, the maximally entangled state of two N-level (N>4) Rydberg atoms can also be obtained. During the passage of the atoms through the cavity field, they are only virtually excited. There is no quantum information that will be transferred from the atoms to the cavity in this case.

Scheme for Implementing Perfect Quantum Teleportation with Non-maximally Entangled W-Class State in Cavity QED

Peng Zhao-Hui, Jia Chun-Xia, Li Jun-Gang

We propose an experimentally feasible teleportation scheme with three-atom W-class state, which was first proposed by Agrawal and Pati [P. Agrawal and A. Pati, Phys. Rev. A 74 (2006) 062320], in cavity QED. In this scheme atoms interact simultaneously with a nonresonant cavity and there is no energy exchange between the atoms and the cavity. Thus it is insensitive to the cavity decay, which is of importance in view of experiment.

A simple scheme is presented for generating three-atom W state via nonresonant Jaynes-Cummings model. In the proposed protocol, it is injected two two-level atom initially prepared in the excited state and ground state through the cavity prepared in the vacuum state. The third two-level atom is prepared in the ground state and three two-level atom are injected into the second cavity prepared in the vacuum state. The experiment of the proposed scheme is feasible.

Teleportation of atomic states via cavity QED for a cavity prepared in a superposition of zero and one Fock states

E. S. Guerra

In this article we discuss two schemes for the teleportation of atomic states. In the first scheme we consider atoms in a three-level cascade configuration and in the second scheme we consider atoms in a three-level lambda configuration. The proposed experimental realization makes use of cavity quantum electrodynamics involving the interaction of Rydberg atoms with a micromaser cavity prepared in a state .
