Query: Generalized Shortcuts to Adiabaticity and Enhanced Robustness Against
  Decoherence   Shortcuts to adiabaticity provide a general approach to mimic adiabatic
quantum processes via arbitrarily fast evolutions in Hilbert space. For these
counter-diabatic evolutions, higher speed comes at higher energy cost. Here,
the counter-diabatic theory is employed as a minimal energy demanding scheme
for speeding up adiabatic tasks. As a by-product, we show that this approach
can be used to obtain infinite classes of transitionless models, including
time-independent Hamiltonians under certain conditions over the eigenstates of
the original Hamiltonian. We apply these results to investigate shortcuts to
adiabaticity in decohering environments by introducing the requirement of a
fixed energy resource. In this scenario, we show that generalized
transitionless evolutions can be more robust against decoherence than their
adiabatic counterparts. We illustrate this enhanced robustness both for the
Landau-Zener model and for quantum gate Hamiltonians.
