Abstract

Abstract We develop a theoretical model for entanglement engineering to generate a multipartite system of field states in high-Q cavities using a cavity-QED. Our model consists of two-level atoms interacting successively with the field inside the arbitrary number of high-Q cavities for pre-calculated interaction times of the atoms with the fields. Controlling these pre-calculated interaction times of the atom-field gives the successful generation of the Greenberg–Horne–Zeilinger (GHZ) state and the W-state in N cavities. We also evaluate the dynamics of entanglement of GHZ entangled field states when they interact with the reservoir.

Entangled Fields in Multiple Cavities by Interaction with One Three-Level Atom

Zhiming Zhan, Jiahua Li, Wen‐Xing Yang +1 more

We present a scheme to entangle fields in multiple cavities. Our scheme is based on the resonant interaction of a Ξ-type three-level atom with the cavity fields for precalculated interaction time, which enables us to generate a quantum entangled Greenberger–Horn–Zeilinger (GHZ) state of fields in multiple cavities. In principle, the scheme can be also generalized to generate N -party GHZ state. The required experimental techniques are within the scope of what can be obtained in the microwave cavity QED set up.

Tripartite entanglement generation using cavity-QED and its dynamics in dissipative environments

Bilal Farooq, Rabia Tahira, Manzoor Ikram

We investigate the generation of tripartite field states inside the high-Q cavities using the cavity QED. The main goal is to successfully generate the entanglement in tripartite systems by passing two-level atoms through three identical high-Q cavities. Our scheme gives the successful generation of entangled tripartite W and GHZ states for pre-determined interaction times of atoms with the cavity fields. The dynamics of initial entangled states is studied as the system evolves in the dissipative environments.

Engineering entanglement between two cavity modes

Manzoor Ikram, Farhan Saif

We present a scheme for the generation of entanglement between different modes of radiation field inside high-$Q$ superconducting cavities. Our scheme is based on the interaction of a three-level atom with the cavity field for precalculated interaction times with each mode. This work enables us to generate a complete set of Bell basis states and a quantum entangled Greenberger-Horn-Zeilinger state.

Scalable cavity-QED-based scheme of generating entanglement of atoms and of cavity fields

Jaehak Lee, Jiyong Park, Sang Min Lee +2 more

We propose a cavity-QED-based scheme of generating entanglement between atoms. The scheme is scalable to an arbitrary number of atoms, and can be used to generate a variety of multipartite entangled states such as the Greenberger-Horne-Zeilinger, $W$, and cluster states. Furthermore, with a role switching of atoms with photons, the scheme can be used to generate entanglement between cavity fields. We also introduce a scheme that can generate an arbitrary multipartite field graph state.

Generation of Different Classes of Multipartite Entanglement Using Cavity-QED

Mustapha Ziane, Rachid El Guerbouz, Fatima-Zahra Siyouri +1 more

Abstract Using a system of cavity quantum electrodynamics (QED) we present two schemes for multipartite entanglement generation. In the first scheme, a three-level atom is interacting with three cavities successively. In the second one, two three-level atoms are interacted with a coherent optical cavity. These protocols allow us to generate the six classes of tripartite entanglement (GHZ, W, A-B-C, AB-C, C-AB, and B-AC class states) by controling the interaction time between atoms and cavities. Moreover, they allow us to generate entanglement between the cavity fields degrees of freedom (from the first scheme), and a mixed entanglement between the cavity field degrees of freedom and the atomic degrees of freedom.

Here we present a quantum electrodynamics model involving a large-detuned single-mode cavity field and n identical two-level atoms. One of its applications for the generation of multiparticle entangled states of various kinds (Greenberger-Horne-Zeilinger states and different class of so-called W states) is analyzed. The theoretical prediction for the model of $n=2$ is made that is consistent with the experimental result by considering the possible three-atom collisions.
