A scheme for realizing arbitrary symmetric Dicke states of multi-qubits via the adiabatic evolution for trapped ions is proposed.Leveraging on the adiabatic operation of dark states,the noise and randomness of moderate fluctuations in experimental parameters is not sensitive in this scheme.The encoded bits can be controlled very well in the cold ion trap.It is almost not affected by the influence of the external environment for quantum operations with higher fidelity.

Key words: quantum adiabatic passage, symmetric Dicke state, dark state, ion trap
