520 _ _ |a 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 possibility of utilizing quantum phase estimation after the quantum annealing process carried out using the kinetic energy part of the Hubbard model as driving Hamiltonian for ground state calculations. We also try to exploit some symmetries in order to reduce size of the Hilbert space and study minimum gap for the same. We further outline our plan to study quantum annealing for a system described by the Hubbard Hamiltonian and coupled to a bath to investigate the effect of the environmental temperature and disorder on the ideal quantum annealing process for finding the ground state.
