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…
Loop-gap Microwave Resonator for Hybrid Quantum Systems
Jason Ball, Yu Yamashiro, Hitoshi Sumiya +5
We designed a loop-gap microwave resonator for applications of spin-based hybrid quantum systems, and tested it with impurity spins in diamond. Strong coupling with ensembles of ni…
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…
