abstract = {Quantum annealing can help in finding the ground state of
Hamiltonians describing many body systems. One such
Hamiltonian is the Fermi-Hubbard Hamiltonian. We investigate
the scaling complexity for the quantum annealing process
carried out using the kinetic energy part of the Hubbard
model as driving Hamiltonian for ground state calculations.
The way we do this is by studying the gaps between the
ground state and the 1st relevant excited state that
participates in the diabatic evolution for a 1-dimensional
system. The behavior of these gaps with increasing system
size could hint at polynomial scaling of required annealing
time for finding the ground state of the Hubbard
Hamiltonian. We also try to extend this idea to a Hubbard
model ladder to learn more about the scaling behavior of
gaps relevant to adiabatic evolution. Further, we discuss
about initial state preparation for the quantum annealing
strategy under study. Information on the complexity coupled
with an efficient way of preparing the initial state could
bolster our hopes for using adiabatic quantum computation
for solving correlated many-body Hamiltonians.},
