A Cavity-QED Scheme for Generating Long-Lived Maximally Entangled States

Abstract

We propose a potentially practical scheme to generate two-atom maximally entangled states by the large-detuning interaction between two three-level Λ-type atoms and coherent optical fields. Conditioned on the results of detecting cavity field, four pairs of atomic maximally entangled states with unity fidelity and high successful probability can be prepared. We also investigate the influence of the cavity dissipation on the generated entangled states and discuss the experimental feasibility of our scheme.

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.

Generation of Entangled Multi-atom Dicke States in Cavity Quantum Electrodynamics

Shu Jing, Zhong Liu

We propose a scheme to generate two-atom maximally entangled state in cavity quantum electrodynamics (QED). The scheme can be extended to generation of entangled multi-atom Dicke states if we control the interaction time of atoms with cavity modes. We use adiabatically state evolution under large atom-cavity detuning, so the scheme is insensitive to atomic spontaneous decay. The influence of cavity decay on fidelity and success probability is discussed.

Generating an entangled coherent state of two cavity modes in a three-level Λ-type atomic system

Qing-Xia Mu, Yonghong Ma, Ling Zhou

In this paper, we present a scheme to generate an entangled coherent state by considering a three-level Λ- type atom interacting with a two-mode cavity driven by classical fields. The two-mode entangled coherent state can be obtained under large detuning conditions. Considering the cavity decay, an analytical solution is deduced.

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.

Preparation of Two-Qutrit Entangled State in Cavity QED

林秀敏, 周正威, 吴玉椿 +2 more

We propose a scheme to generate a 3 x 3-dimensional maximally entangled state of two particles. Two three-level atoms interact with a strongly detuned cavity so that the cavity is only virtually excited and efficient decoherence time of the cavity is greatly prolonged. Compared to other protocols, this protocol is simpler and has a higher fidelity.
