Quantum annealing of the -spin model under inhomogeneous transverse field driving
Yuki Susa, Yu Yamashiro, Masayuki Yamamoto +3
We solve the mean-field-like -spin Ising model under a spatio-temporal inhomogeneous transverse field to study the effects of inhomogeneity on the performance of quantum anneali…
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…
Nested Quantum Annealing Correction at Finite Temperature: -spin models
Shunji Matsuura, Hidetoshi Nishimori, Walter Vinci +1
Quantum annealing in a real device is necessarily susceptible to errors due to diabatic transitions and thermal noise. Nested quantum annealing correction is a method to suppress e…
Exponential Speedup of Quantum Annealing by Inhomogeneous Driving of the Transverse Field
Yuki Susa, Yu Yamashiro, Masayuki Yamamoto +1
We show, for quantum annealing, that a certain type of inhomogeneous driving of the transverse field erases first-order quantum phase transitions in the p-body interacting mean-fie…
