This study delves into the intricate dynamics of quantum coherence in modulated systems, particularly focusing on neutrino oscillations and quantum emitters subjected to external driving fields. Utilizing Floquet theory, we examine the modulation of electron wavefunctions and its implications for quantum state preparation, coherence preservation, and applications in quantum computing and astrophysics. Our findings highlight the extended coherence scales in spin-flavor oscillations compared to flavor oscillations, suggesting potential advancements in quantum information technologies.
