We　propose　a　scheme　to　drive　the　centre-of-mass　vibrational　motion　of　two　trapped　ions　to　an　arbitrary　finite　superposition　of　Fock　states　from　the　vacuum　state.　In　order　to　generate　a　superposition　of　N　Fock　states　we　need　N　operations.　The　scheme　does　not　require　differential　laser　addressing　of　individual　ions.
