摘要

Fine control of the dynamics of a quantum system is the key element to perform quantum information processing and coherent manipulations for atomic and molecular systems.We propose a control protocol using a tangentpulse driven model and demonstrate that it indicates a desirable design,i.e.,of being both fast and accurate for population transfer.As opposed to other existing strategies,a remarkable character of the present scheme is that high velocity of the nonadiabatic evolution itself not only will not lead to unwanted transitions but also can suppress the error caused by the truncation of the driving pulse.
