  Applying time-dependent driving is a basic way of quantum control. Driven
systems show various dynamics as its time scale is changed due to the different
amount of nonadiabatic transitions. The fast-forward scaling theory enables us
to observe slow (or fast) time-scale dynamics during moderate time by applying
additional driving. Here we discuss its application to nonadiabatic
transitions. We derive mathematical expression of additional driving and also
find a formula for calculating it. Moreover, we point out relation between the
fast-forward scaling theory for nonadiabatic transitions and shortcuts to
adiabaticity by counterdiabatic driving.
