    "abstract": "We suggest using the method of quantum annealing for computing the ground\nstate of the Heisenberg spin chains. Our initial Hamiltonian describes a spin\nsystem in a highly non-uniform magnetic field. The initial Hamiltonian\ngradually transforms into the Heisenberg Hamiltonian, which describes the\nexchange interaction and the Zeeman interaction with the uniform magnetic\nfield. We demonstrate quantum annealing for 2-, 3-, and 9-spin systems. In\nparticular, we consider the alternate (ferro- and antiferromagnetic) exchange\nintegral. By changing the sign of the exchange integrals we switch from the\nfrustrated to the corresponding non-frustrated spin system. We discuss the\nsimilarity and difference between the frustrated and non-frustrated spin\nsystems.",
