abstract = {Lattice QCD in the strong coupling regime can be formulated
in dual variables, which are integer-valued. It can be
efficiently simulated for modest finite temperatures and
finite densities via the worm algorithm, circumventing the
finite density sign problem in this regime. However, the low
temperature regime is more expensive to address. As the
partition function is solely expressed in terms of integers,
it can be cast as a combinatorial optimization problem that
can be solved on a quantum annealer. We will first explain
the setup of the system we want to study and then present
its reformulation suitable for a quantum annealer, and in
particular the D wave. As a proof of concept, we present
first results obtained on D wave for gauge group U(1) and
U(3), and outline the next steps towards gauge groups SU(3).
We find that in addition, histogram reweighting greatly
improves the accuracy of our observables when compared to
analytic results.},
