The non-Markovianity of open quantum dynamics can give rise to the oscillation of quantum coherence in time, and the interference between oscillations leads to quantum beat of coherence. We design two dynamical models of open quantum systems for revealing this kind of phenomenon of quantum interference, analyze the forming process and the producing conditions of the quantum beats.
