Dynamics of reverse annealing for the fully-connected -spin model
Yu Yamashiro, Masaki Ohkuwa, Hidetoshi Nishimori +1
Reverse annealing is a relatively new variant of quantum annealing, in which one starts from a classical state and increases and then decreases the amplitude of the transverse fiel…
Reverse annealing for the fully connected -spin model
Masaki Ohkuwa, Hidetoshi Nishimori, Daniel A. Lidar
Reverse annealing is a variant of quantum annealing that starts from a given classical configuration of spins (qubits). In contrast to the conventional formulation, where one start…
Exact expression of the energy gap at first-order quantum phase transitions of a non-stoquastic Hamiltonian
Masaki Ohkuwa, Hidetoshi Nishimori
We study the energy gap between the ground state and the first excited state of a mean-field-type non-stoquastic Hamiltonian by a semi-classical analysis. The fully connected mean-…
