We　propose　a　scheme　to　produce　quantum　phase　gates　for　trapped　ions.　Taing　advantage　of　the　adiabatic　evolution,　the　operation　is　insensitive　to　small　fluctuations　of　experimental　parameters.　Furthermore,　the　spontaneous　emission　is　suppressed　since　the　ions　have　no　probability　of　being　populated　in　the　electronic　excited　states.　©　International　Academic　Publishers.
