【摘要】 The preparation and transfer of entanglement in atomic ensembles interacting with cavity fields is investigated.The results show that two pairs of quasi-Bell states(entangled coherent states) between two atomic ensembles can be explicitly generated through quasi-Bell measurements on cavity fields.It is also indicated that the quantum entanglement between two cavity fields can be perfectly transferred into two atomic ensembles.
