The agreement between quantum trajectoires and quantum wavepacket dynamics is excellent all along the simulated dynamics, even though the time-dependent potentials show complex interferences at long times due to the reduced dimensionality of the model. Despite this complex dynamical features, the approximate trajectorybased schemes CT-MQC and CT-TSH are in close agreement to quantum results, i.e., trajectories and wavepackets. Furthermore, CT-TSH shows a slightly improved quantitative agreement with the reference over CT-MQC.
