Generation of multipartite entanglement between spin-1 particles with bifurcation-based quantum annealing
Yuichiro Matsuzaki, Takashi Imoto, Yuki Susa
Quantum annealing is a way to solve a combinational optimization problem where quantum fluctuation is induced by transverse fields. Recently, a bifurcation-based quantum annealing…
Variational optimization of the quantum annealing schedule for the Lechner-Hauke-Zoller scheme
Yuki Susa, Hidetoshi Nishimori
The annealing schedule is optimized for a parameter in the Lechner-Hauke-Zoller (LHZ) scheme for quantum annealing designed for the all-to-all-interacting Ising model representing…
Probing the Universality of Topological Defect Formation in a Quantum Annealer: Kibble-Zurek Mechanism and Beyond
Yuki Bando, Yuki Susa, Hiroki Oshiyama +7
The number of topological defects created in a system driven through a quantum phase transition exhibits a power-law scaling with the driving time. This universal scaling law is th…
Performance enhancement of quantum annealing under the Lechner-Hauke-Zoller scheme by non-linear driving of the constraint term
Yuki Susa, Hidetoshi Nishimori
We analyze the performance of quantum annealing as formulated by Lechner, Hauke, and Zoller (LHZ), by which a Hamiltonian with all-to-all two-body interactions is reduced to a corr…
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…
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…
