Graph minor embedding can affect sampling degenerate ground states using quantum annealing
Naoki Maruyama, Masayuki Ohzeki, Kazuyuki Tanaka
Quantum annealing, as currently implemented in hardware, cannot fairly sample all ground states. Graph minor embedding, which maps a problem to the hardware graph of quantum anneal…
Benchmark test of Black-box optimization using D-Wave quantum annealer
Ami S. Koshikawa, Masayuki Ohzeki, Tadashi Kadowaki +1
In solving optimization problems, objective functions generally need to be minimized or maximized. However, objective functions cannot always be formulated explicitly in a mathemat…
Assessment of image generation by quantum annealer
Takehito Sato, Masayuki Ohzeki, Kazuyuki Tanaka
Quantum annealing was originally proposed as an approach for solving combinatorial optimisation problems using quantum effects. D-Wave Systems has released a production model of qu…
Teacher-student learning for a binary perceptron with quantum fluctuations
Shunta Arai, Masayuki Ohzeki, Kazuyuki Tanaka
We analysed the generalisation performance of a binary perceptron with quantum fluctuations using the replica method. An exponential number of local minima dominate the energy land…
Mean field analysis of reverse annealing for code-division multiple-access multiuser detection
Shunta Arai, Masayuki Ohzeki, Kazuyuki Tanaka
We evaluate the typical ARA performance of the CDMA multiuser detection by means of statistical mechanics using the replica method. At first, we consider the oracle cases where the…
A two-stage data-analysis method for total-reflection high-energy positron diffraction (TRHEPD)
Kazuyuki Tanaka, Izumi Mochizuki, Takashi Hanada +3
Total-reflection high-energy positron diffraction (TRHEPD) is a novel experimental method for the determination of surface structure, which has been extensively developed at the Sl…
