Table : Time rescaling t f in fs for each calculation presented on figure . Continuous lines represent TDQT results, and in all cases along the dynamics they remain smaller than the dotted lines, representing TDCT results. The figure attests to the improvement in numerical accuracy that TDQT can provide over TDCT, even insofar as reproducing wavepacket dynamics is concerned. It should also be remembered that the TDCT calculations were performed using more than one order of magnitude more trajectories than the TDQT calculations.
