Abstract
Taking into account the controlling over average circulating supercurrent, we theoretically investigate the dynamic features of the superconducting charge qubit driven by ac gate voltage. By means of treating ac voltage as a perturbation and considering the nonadiabatic case, the average circulating supercurrents are obtained with/without the effect of decoherence and dissipative factors. It is found that average circulating supercurrents can be controlled for above two cases by modulating the frequency of ac voltage.
