We　propose　a　way　to　prepare　W　state　among　atomic　ensembles　via　stimulated　Raman　adiabatic　passage　(STIRAP)　technique.　The　atomic　ensembles　are　trapped　in　spatially　separated　cavities　collectively　linked　to　another　cavity　trapping　a　single　atom　by　optical　fibers.　Our　strictly　numerical　simulations　show　that,　the　atomic　spontaneous　emission,　the　cavity　decay　and　the　fiber　loss　are　efficiently　suppressed　by　the　engineering　adiabatic　passage.　The　method　can　be　generalized　to　prepare　W　state　among　any　number　of　atomic　ensembles.　We　believe　that　our　proposal　will　promote　development　of　quantum　teleportation,　especially　quantum　state　engineering　of　multi-target-qubit　collectively　controlled　by　a　qubit.　©　2013　Elsevier　B.V.　All　rights　reserved.
