  The dynamics of a quantum phase transition is inextricably woven with the
formation of excitations, as a result of the critical slowing down in the
neighborhood of the critical point. We design a transitionless quantum driving
through a quantum critical point that allows one to access the ground state of
the broken-symmetry phase by a finite-rate quench of the control parameter. The
method is illustrated in the one-dimensional quantum Ising model in a
transverse field. Driving through the critical point is assisted by an
auxiliary Hamiltonian, for which the interplay between the range of the
interaction and the modes where excitations are suppressed is elucidated.
