In this paper, we demonstrate transient dynamics of Husimi Q-representationto visualize and characterize the phase synchronization behavior of a two-levelsystem (qubit) driven by a laser field in both the Markov and non-Markovregime. In the Markov regime, phase preference of the qubit goes away in thelong time limit, whereas the long-time phase localization persists in thenon-Markovian regime. We also plot the maximum of the shifted phasedistribution in two different ways: (a) by varying the detuning and laser drivestrength, and (b) by varying the system-bath coupling and laser drive strength.Signature of quantum phase synchronization viz. the Arnold tongue isdemonstrated through the maximal value of the shifted phase distribution. Thephase synchronization is observed inside the tongue region while the regionoutside the tongue is desynchronized. The synchronization regions aredetermined by various system-environment parameters and the qubit phasesynchronization is shown to be enhanced in the non-Markov regime.
