We investigate the dynamics of quantum scrambling, characterized by theout-of-time ordered correlators (OTOCs), in a non-Hermitian quantum kickedrotor subjected to quasi-periodical modulation in kicking potential.Quasi-periodic modulation with incommensurate frequencies creates ahigh-dimensional synthetic space, where two different phases of quantumscrambling emerge: the freezing phase characterized by the rapid increase ofOTOCs towards saturation, and the chaotic scrambling featured by the lineargrowth of OTOCs with time. We find the dynamical transition from the freezingphase to the chaotic scrambling phase, which is assisted by increasing the realpart of the kicking potential along with a zero value of its imaginary part.The opposite transition occurs with the increase in the imaginary part of thekicking potential, demonstrating the suppression of quantum scrambling bynon-Hermiticity. The underlying mechanism is uncovered by the extension of theFloquet theory. Possible applications in the field of quantum information arediscussed.
