QUBO-Based Optimization of Social Indicator Configurations for Working-Age Population Growth

Hayate Wada, Seiya Miyamoto, Tatsumasa Ogawa +3

The paper introduces a QUBO-based framework that models and optimizes combinations of municipal social indicators to predict and maximize working‑age population growth, using regre…

Interpretation of Unfair Sampling in Quantum Annealing by Node Centrality

Naoki Maruyama, Masayuki Ohzeki

In applications where multiple optimal solutions are needed, transverse-field quantum annealing (QA) is known to sample degenerate ground states in a strongly biased manner. Despit…

Quantum-classical hybrid algorithm using quantum annealing for multi-objective job shop scheduling

Kenta Sawamura, Kensuke Araki, Naoki Maruyama +2

Efficient production planning is essential in modern manufacturing to improve performance indicators such as lead time and to reduce reliance on human intuition. While mathematical…

Uniformity Bias in Ground-State Sampling Induced by Replica Alignment in Quantum Monte Carlo for Quantum Annealing

Naoki Maruyama, Masayuki Ohzeki, Kazuyuki Tanaka

Quantum annealing (QA) with a transverse field often fails to sample degenerate ground states fairly, limiting applicability to problems requiring diverse optimal solutions. Althou…

Typical reconstruction limit and phase transition of maximum entropy method

Masaru Hitomi, Masayuki Ohzeki

We investigate the dependence of the maximum entropy method (MEM) reconstruction performance on the default model. The maximum entropy method is a reconstruction technique that uti…
