abstract = {We want to illustrate how to find the ground state of the
one-dimensional Hubbard model. We start by introducing the
classical algorithms that can do this, like exact
diagonalization, Lanczos algorithm and the Bethe-ansatz
equations. Subsequently, we show how to solve the problem on
a gate-based quantum computer using the quantum annealing
algorithm. The procedure involves transforming the fermionic
Hamiltonian using the Jordan-Wigner transformation,
preparing the initial state for quantum annealing using
Givens rotations, and constructing the circuit for the time
evolution according to the Schrodinger equation using the
second-order product-formula algorithm. We conclude by
presenting some results and analysis of performance for the
quantum annealing algorithm.},
