  In fast forward quantum shortcuts to adiabaticity, a designed potential
$U_{FF}(q,t)$ steers a wavefunction to evolve from the $n$'th eigenstate of an
initial Hamiltonian $\hat H(0)$ to the $n$'th eigenstate of a final Hamiltonian
$\hat H(\tau)$, in finite time $\tau$. Previously proposed strategies for
constructing $U_{FF}$ are (in the absence of special symmetries) limited to the
ground state, $n=0$. We develop a method that overcomes this limitation,
thereby substantially expanding the applicability of this shortcut to
adiabaticity, and we illustrate its effectiveness with numerical simulations.
Semiclassical analysis provides insight and establishes a close correspondence
with the analogous classical fast forward method.
