摘要: We consider the population and decay of a qubit under electromagnetic environment. Employing timeconvolutionless master equation, we investigate Markovian non-Markovian behaviour corresponding perturbation expansion. The Jaynes-Cummings model on resonance is investigated. Some figures clearly show different evolution behaviours. reasons are interpreted in paper.
