abstract = {We determine the classical and quantum complexities of a
specific ensemble of three-satisfiability problems with a
unique satisfying assignment for up to N = 100 and 80
variables, respectively. In the classical limit, we employ
generalized ensemble techniques and measure the time that a
Markovian Monte Carlo process spends in searching classical
ground states. In the quantum limit, we determine the
maximum finite correlation length along a quantum adiabatic
trajectory determined by the linear sweep of the adiabatic
control parameter in the Hamiltonian composed of the problem
Hamiltonian and the constant transverse field Hamiltonian.
In the median of our ensemble, both complexities diverge
exponentially with the number of variables. Hence, standard,
conventional adiabatic quantum computation fails to reduce
the computational complexity to polynomial. Moreover, the
growth-rate constant in the quantum limit is 3.8 times as
large as the one in the classical limit, making classical
fluctuations more beneficial than quantum fluctuations in
ground-state searches.},
