Control of automated guided vehicles without collision by quantum annealer and digital devices
Masayuki Ohzeki, Akira Miki, Masamichi J. Miyama +1
We formulate an optimization problem to control a large number of automated guided vehicles in a plant without collision. The formulation consists of binary variables. A quadratic…
Steady state distributions of network of degenerate optical parametric oscillators in solving combinatorial optimization problems
Ryoji Miyazaki, Masayuki Ohzeki
We investigate network of degenerate optical parametric oscillators (DOPOs) as a model of the coherent Ising machine, an architecture for solving Ising problems. The network repres…
Comment on "Energy-time uncertainty relation for driven quantum systems" and "Quantum Speed Limit for Non-Markovian Dynamics"
Manaka Okuyama, Ryo Takahashi, Masayuki Ohzeki
Deffner and Lutz [J. Phys. A 46, 335302 (2013) and Phys. Rev. Lett. 111, 010402 (2013).] extended the Mandelstam-Tamm bound and the Margolus-Levitin bound to time-dependent and non…
Difference between quantum annealing by imaginary-time and real-time Schrödinger equation of Grover's search
Shuntaro Okada, Masayuki Ohzeki, Kazuyuki Tanaka
We confirmed the annealing time of Grover's search which is required to obtain desired success probability for quantum annealing by the imaginary-time and the real-time Schrödinger…
