Entanglement swapping between atom and cavity and generation of entangled state of cavity fields
Ai-Xi Chen, Li Deng · Chinese Physics · 2007
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.
