摘要
We propose two schemes for deterministically generating three-partite Greenberger-Horne-Zeilinger (GHZ) and W states of distant atoms based on the selective photon emission and absorption processes. In our schemes, it is found that the effects of atomic spontaneous decay and photon leakage out of fiber are suppressed effectively due to the presences of dispersive atom-field interaction and strong cavity-fiber coupling intensity. To check the experimental feasibility of our schemes, we also numerically simulated the effects of photon leakage out of the cavities, and the numerical simulation shows that our proposal is good enough to demonstrate the generation of three-partite GHZ and W states of distant atoms with high fidelity. In addition, the present schemes can also be generalized to prepare N-partite W state of distant atoms.
