We propose a scheme for the generation of an arbitrary quantum states for multiple trapped ions in the symmetric Dicke subspace. One can manipulate the collective ion transition in a selective symmetric Dicke subspace via the virtual excitation induced inequidistant energy levels. All the states undergo the same phonon-number-dependent Stark shift and thus the scheme is insensitive to the thermal motion. Furthermore, the scheme does not require individual addressing of the ions.
