Abstract
The quantum correlation in dephasing decay can be realized, when the energy fluctuations of transition frequencies are synchronized. The correlation in the three-level atom systems will enhance the interference in the absorption and change the nature of the interference, from destructive to constructive in cascade low-driving three-level atom and from constructive to destructive in V-type three-level atom. The quantum correlation is observed by properly introducing the collision or time-dependent magnetic field through the increase or decrease of the resonant absorption.
