A　scheme　is　presented　for　realizing　quantum　logic　gate　in　an　ion　trap.　In　the　scheme　the　state　of　the　mth　ion　is　first　replicated　onto　the　collective　motion.　Then　a　transformation,　conditional　on　the　motional　state,　is　performed　on　the　nth　ion.　Finally　the　motional　state　is　replicated　back　onto　the　mth　ion.　By　this　way　the　quantum　logic　Sate　between　the　mth　and　the　nth　ions　is　realized.　The　scheme　does　not　put　any　requirement　on　the　Lamb-Dicks　parameter.
