We have studied the collective decoherence dynamics of a quantum register coupled with a thermal environment. It is shown that by applying a spin-flipping radiofrequency pulse sequence, the Lamb phase shift, as well as the phase damping, of the quantum register become controllable and the coherence of the quantum register is recovered.
