Abstract

We discuss the generation of a macroscopic entangled state in a single atom cavity-QED system. The three-level atom in a cascade configuration interacts dispersively with two classical coherent fields inside a doubly resonant cavity. We show that a macroscopic entangled state between these two cavity modes can be generated under large detuning conditions. The entanglement persists even under the presence of cavity losses.

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

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.

A macroscopical entangled coherent state generator in a V configuration atom system

Ling Zhou, Han Xiong

In this paper, we propose a scheme to produce a pure and macroscopically entangled coherent state. When a three-level 'V' configuration atom interacts with a doubly resonant cavity, under a strong classical driven condition, an entangled coherent state can be generated from vacuum fields. An analytical solution for this system in the presence of cavity losses is also given.

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.

Two-mode single-atom laser as a source of entangled light

Martin Kiffner, Muhammad Suhail Zubairy, Jörg Evers +1 more

A two-mode single-atom laser is considered, with the aim of generating entanglement in macroscopic light. Two transitions in the four-level gain medium atom independently interact with the two cavity modes, while two other transitions are driven by control laser fields. Atomic relaxation as well as cavity losses are taken into account. We show that this system is a source of macroscopic entangled light over a wide range of control parameters and initial states of the cavity field.

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.

Generation of multipartite entangled states by cavity QED

Zhang Ying-Jie, Ren Ting-Qi, Yun‐Jie Xia

We propose the methods of generating multipartite entanglement by considering the interaction of a system of N two-level atoms in M cavities of high quality factor with a strong classical driving field. It is shown that, with the cavity detuning, the applied driving field detuning and vacuum Rabi coupling, we can produce an entangled coherent state in two single-mode cavities and generate the entangled coherent cluster states in two bimodal vacuum cavities. Tuning these parameters also allows us to acquire the anti-Jaynes–Cummings (AJC) interaction, with which we can generate the maximally two-photon entangled states, and the two-atom and the two-photon entangled cluster states.
