  The Quantum Speed Limit can be found in many different situations, in
particular in the propagation of information through quantum spin chains. In
homogeneous chains it implies that taking information from one extreme of the
chain to the other will take a time $O(N/2)$, where $N$ is the chain length.
Using Optimal Control Theory we design control pulses that achieve near perfect
population transfer between the extremes of the chain at times on the order of
$N/2$, or larger, depending on which features of the transfer process are to be
studied. Our results show that the control pulses that govern the dynamical
behaviour of chains with different lengths are closely related, that larger
control times imply more complicated control pulses than those found at times
on the order of $N/2$ and also larger driving energies. The pulses were
constructed for control schemes involving one or two actuators in chains with
exchange couplings without static disorder. Our results also show that the two
actuator scheme is considerably more robust against the presence of static
disorder than the scheme that uses just a single one.
