We　propose　a　simple　scheme　for　deterministic　and　multi-controlled　teleportation　of　an　arbitrary　unknown　two-level　two-ion　state　in　ion-trap　system.　In　the　scheme,　the　special　entangled　W　states　used　as　quantum　channels　and　the　requisite　unitary　transformations　may　be　achieved　via　a　single　resonant　interaction,　respectively.　The　required　time　to　complete　the　whole　procedure　does　not　increase　with　the　number　of　agents.　©　2010　Chinese　Physical　Society　and　IOP　Publishing　Ltd.
