N2 - We study the non-Markovian dynamics of multilevel quantum systems coupled with a bosonic dissipative environment. Based on the known exact quantum-state diffusion (QSD) equations, we propose a systematic approach to derive exact time-convolutionless master equations for multilevel quantum systems. Through a combination of analytical and numerical approaches, we extract the non-Markovian dynamics of quantum interfer-ence in different time scales. Also, we demonstrate the evolution of quantum interference in a four-level system controlled by an external electromagneticfield. Our findings are extended to few-body quantum networks, with a universal formalism established.
