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…
Griffiths-McCoy singularity on the diluted Chimera graph: Monte Carlo simulations and experiments on the quantum hardware
Kohji Nishimura, Hidetoshi Nishimori, Helmut G. Katzgraber
The Griffiths-McCoy singularity is a phenomenon characteristic of low-dimensional disordered quantum spin systems, in which the magnetic susceptibility shows singular behavior as a…
Counterdiabatic Hamiltonians for multistate Landau-Zener problem
Kohji Nishimura, Kazutaka Takahashi
We study the Landau-Zener transitions generalized to multistate systems. Based on the work by Sinitsyn et al. [Phys. Rev. Lett. 120, 190402 (2018)], we introduce the auxiliary Hami…
Quantum annealing with a nonvanishing final value of the transverse field
Kohji Nishimura, Hidetoshi Nishimori
We study the problem to infer the original ground state of a spin-glass Hamiltonian out of the information from the Hamiltonian with interactions deviated from the original ones. O…
Retrieving the ground state of spin glasses using thermal noise: Performance of quantum annealing at finite temperatures
Kohji Nishimura, Hidetoshi Nishimori, Andrew J. Ochoa +1
We study the problem to infer the ground state of a spin-glass Hamiltonian using data from another Hamiltonian with interactions disturbed by noise from the original Hamiltonian, m…
