Hybrid Algorithm of Linear Programming Relaxation and Quantum Annealing
Taisei Takabayashi, Masayuki Ohzeki
The demand for classical-quantum hybrid algorithms to solve large-scale combinatorial optimization problems using quantum annealing (QA) has increased. One approach involves obtain…
Quadratic Unconstrained Binary Formulation for Traffic Signal Optimization on Real-World Maps
Reo Shikanai, Masayuki Ohzeki, Kazuyuki Tanaka
The D-Wave quantum annealing machine can quickly find the optimal solution for quadratic unconstrained binary optimization (QUBO). One of the applications where the use of quantum…
Efficient Algorithm for Binary Quadratic Problem by Column Generation and Quantum Annealing
Sota Hirama, Masayuki Ohzeki
We propose an efficient algorithm that combines column generation and quantum annealing to solve binary quadratic problems. Binary quadratic problems are difficult to solve because…
Virtual Screening of Chemical Space based on Quantum Annealing
Takuro Tanaka, Masami Sako, Mahito Chiba +3
For searching a new chemical material which satisfies the target characteristic value, for example emission wavelength, many cut and trial of experiments/calculations are required…
Online calibration scheme for training restricted Boltzmann machines with quantum annealing
Takeru Goto, Masayuki Ohzeki
We propose a scheme to calibrate the internal parameters of a quantum annealer to obtain well-approximated samples for training a restricted Boltzmann machine (RBM). Empirically, s…
Kernel Learning by quantum annealer
Yasushi Hasegawa, Hiroki Oshiyama, Masayuki Ohzeki
The Boltzmann machine is one of the various applications using quantum annealer. We propose an application of the Boltzmann machine to the kernel matrix used in various machine-lea…
Magnetic order in nanoscale gyroid networks
Ami S. Koshikawa, Justin Llandro, Masayuki Ohzeki +3
Three-dimensional magnetic metamaterials feature interesting phenomena that arise from a delicate interplay of material properties, local anisotropy, curvature, and connectivity. A…
Threshold theorem in quantum annealing with deterministic analog control errors
Manaka Okuyama, Masayuki Ohzeki
We investigate the effect of deterministic analog control errors in the time-dependent Hamiltonian on isolated quantum dynamics. Deterministic analog control errors are formulated…
Mean-field theory is exact for Ising spin glass models with Kac potential in non-additive limit on Nishimori line
Manaka Okuyama, Masayuki Ohzeki
Recently, Mori [Phys. Rev. E 84, 031128 (2011)] has conjectured that the free energy of Ising spin glass models with the Kac potential in the non-additive limit, such as the power-…
