Abstract

We propose a scheme to create universal Dicke states of n largely detuned atoms through detecting the leaky photons from an optical cavity. The generation of entangled states in our scheme has quasi-unit success probability, so it has potential practicability based on current or near coming laboratory cavity QED technology.

Generation of multi-atom Dicke states through the detection of cavity decay

We propose a scheme to create W states, and further generalize universal Dicke states of n largely detuned atoms, through detecting the leaky polarized photons from an optical cavity. The generation of entangled states in our scheme has a very high success probability since the atomic spontaneous emission is strongly suppressed. The scheme has potential practicability based on near coming laboratory cavity QED technology.

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.

The generation of multi-atom entanglement via the detection of cavity decay

Boyang Yu, Zhi‐Yuan Zhou, Guang-Can Guo

We propose a scheme to generate entangled states of multi-Λ-type three-level atoms in a cavity. It is shown how multi-atom Dicke states can be prepared simply by detecting the photon decays from the cavity. The analytic form of the approximate efficiency of the scheme is obtained. With this analytic form investigated, we provide an active way to achieve high efficiency.

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

Shao-Hua Xiang, Shao Bin, Kehui Song +1 more

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.

A scheme for preparation of multi-atom entanglement by detecting the cavity decay and analysis of its implementation

L.-M. Duan, Harry J. Kimble

We give the detailed study of a scheme to efficiently engineer multi-atom entanglement by detecting the cavity decay through single-photon detectors. The scheme can be used to prepare arbitrary superpositions of multi-atom Dicke states, without the requirements of high-efficiency detection, separate addressing of different atoms, and full localization of the atoms to the Lamb-Dicke limit. We analyze in detail various sources of noise and imperfections in this experimental scheme, and show that the scheme is robust to the dominant sources of noise and realizable with the state of the art technology.

Generating four-mode multiphoton entangled states in cavity QED

Jing Shu, Xu‐Bo Zou, Yun‐Feng Xiao +1 more

We propose a scheme to generate four-mode multiphoton entangled states by passing $N$ identical atoms through two high-$Q$ cavities in turn. In the case of $N=1$, the scheme can deterministically generate Einstein-Podosky-Rosen entangled photon pairs. We use adiabatical 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 also discussed.
