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…
