This paper proposes a scheme where entanglement swapping between atom and cavity can be realized. Λ-type three-level atoms interacting resonantly with cavity field are considered. By detecting atom and cavity field, it realizes entanglement swapping between atom and cavity. It uses the technique of entanglement swapping to generate an entangled state of two cavity fields by measuring on atoms. It discusses the experimental feasibility of the proposed scheme and application of entangled state of cavity fields.This paper proposes a scheme where entanglement swapping between atom and cavity can be realized.

Generation of Entangled W State via Entangled GHZ State in the Single Mode Cavity Field

Qingqiang Kuang

Entangled W state can be applied to quantum information processing in the quantum entanglement,and presented a scheme generation of entangled W state via entangled GHZ state in the single mode cavity field.Three two-level atoms(1,2,3) initially in the W entanglement state,then two atoms 2 and 3 are injected into single mode cavity field to make interaction,while atom 1 is far from the cavity field.The result shows that entangled W state can be generated by manipulating the interactions between cavity field and two atoms in appropriate coupling coefficients when atom 1 is be detected.Entangled W state can be applied to quantum information processing in the quantum entanglement,and presented a scheme generation of entangled W state via entangled GHZ state in the single mode cavity field.Three two-level atoms(1,2,3) initially in the W entanglement state,then two atoms 2 and 3 are injected into single mode cavity field to make interaction,while atom 1 is far from the cavity field.The result shows that entangled W state can be generated by manipulating the interactions between cavity field and two atoms in appropriate coupling coefficients when atom 1 is be detected.

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.We propose a cavity-QED-based scheme of generating entanglement between atoms.
