摘要：
We investigate the relation between the single-particle coherence and the reciprocal of the mean quantum Fisher information per particle (RMQFI) in Bose-Einstein condensates (BECs) in the presence of interatomic interaction and interspecies interaction. The single-particle coherence and RMQFI depend on the interatomic interaction. It is shown that the larger interatomic interaction more rapidly induces entanglement.
