Two-parameter counter-diabatic driving in quantum annealing
Luise Prielinger, Andreas Hartmann, Yu Yamashiro +3
We introduce a two-parameter approximate counter-diabatic term into the Hamiltonian of the transverse-field Ising model for quantum annealing to accelerate convergence to the solut…
Mean-Field Solution of the Weak-Strong Cluster Problem for Quantum Annealing with Stoquastic and Non-Stoquastic Catalysts
Kabuki Takada, Yu Yamashiro, Hidetoshi Nishimori
We study the weak-strong cluster problem for quantum annealing in its mean-field version as proposed by Albash [Phys. Rev. A 99 (2019) 042334] who showed by numerical diagonalizati…
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…
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…
