摘要: We calculate the geometric phase of a spin-$1/2$ system driven by one and two mode quantum fields subject to decoherence. Using jump approach, we show that corrections in no-jump trajectory are different when considering adiabatic nonadiabatic evolutions. discuss implications our results from both fundamental as well computational perspectives.
