Many-body transverse interactions in the quantum annealing of the p-spin ferromagnet
arXiv:1207.2909 · doi:10.1088/1751-8113/45/43/435301
Abstract
We study the performance of quantum annealing for the simple -body infinite-range ferromagnetic Ising model. In particular, we generalize the transverse antiferromagnetic interactions proposed by Seki and Nishimori as a quantum driver to many-body transverse interactions to understand if the two-body interactions are essential to allow the system to avoid troublesome first-order quantum phase transitions. We conclude that the general many-body interactions are effective to let the system evolve only through second-order transitions as long as a few minor conditions are satisfied. It is also discussed whether the overlap of the ground-state wave function of the new driver term with the target ground state is an essential factor for the success.
