Production of Entanglement of Multiple Three-Level Atoms with a Two-Mode Cavity

Abstract

A scheme is proposed for generating maximally entangled states for two or more three-level atoms. In the scheme the atoms are sent through a two-mode cavity one by one and interact with the two-cavity modes sequentially. The required experimental techniques are within the scope of what can be obtained in the microwave cavity QED setup.

Method for generating maximally entangled states of multiple three-level atoms in cavity QED

Guang-Sheng Jin, Shu‐Shen Li, Songlin Feng +1 more

We propose a scheme to generate maximally entangled states (MESs) of multiple three-level atoms in microwave cavity QED based on the resonant atom-cavity interaction. In the scheme, multiple three-level atoms initially in their ground states are sequently sent through two suitably prepared cavities. After a process of appropriate atom-cavity interaction, a subsequent measurement on the second cavity field projects the atoms onto the MESs. The practical feasibility of this method is also discussed.

One-step implementation of maximally entangled states of many three-level atoms in microwave cavity QED

Xu‐Bo Zou, Wolfgang M. Mathis

We propose an experimental scheme for one-step implementation of maximally entangled states of many three-level atoms in microwave cavity QED. In the scheme, many three-level atoms initially prepared in the same superposition states are simultaneously sent through one superconducting cavity, and maximally entangled states can be generated without requiring the measurement and individual addressing of the atoms.

Production of Three-Dimensional Maximal Entanglement for Two Cavity Modes

Zheng Shi-Biao

A scheme is proposed for generating maximally entangled states for two cavity modes, with each containing no more than two photons. In the scheme a single atom is sent through two resonant single-mode cavities. Based on the presently available techniques, our scheme might be experimentally realizable.

Preparation of multiple separate cavity fields entanglement in cavity QED

Xiang Liu

We present a scheme to produce a maximally entangled state of multiple separate cavity fields based on the resona'nt interaction of a single-mode cavity field and a three-level atom. Firstly we investigate the entanglement of two separate cavity fields, and then generalize this scheme with maximally entangled states to multiple separate cavity fields.

Efficient generation of Bell-cat states in remote cavities

Ying Zhang

In the context of cavity quantum electrodynamics (QED),a potential scheme is proposed to generate entangled coherent states. The scheme includes twice interactions of two-level atoms with cavities. In the first interaction,two atoms are sent into a microwave cavity with the large detuning respectively. And then the second interaction is that the two atoms enter another microwave cavity and are driven by a resonant classical field meantime. When we choose the proper interaction time and make measurement on the two atoms,the two microwave cavity mode fields are determinatively entangled. In addition,it is easy to generalize the scheme to multi-cavity and multi-atom.

Generation of two-mode entangled coherent states via a cavity QED system

Qing-Xia Mu, Yonghong Ma, Ling Zhou

A scheme is presented for the generation of entangled coherent states in a single-atom cavity-QED system. In the scheme, a three-level V -type atom interacts dispersively with a two-mode cavity and is driven by a classical field. We show that under large detuning conditions the cavity field can evolve into maximally entangled coherent states when one cavity mode is initially prepared in an odd coherent state. The effect of the cavity losses on the entanglement is also studied.
