다국어 초록 (Multilingual Abstract)

D-Wave quantum annealers offer the lowest possible energy for combinatorial optimization problems via the quantum adiabatic process, while the accuracy of their results is dependent on various parameters such as the embedding chain strength and the annealing time. In this study, we controlled the annealing time, annealing schedule, and reversible adiabatic process to observe the accuracy of the quantum annealing measurement in each situation on a D-Wave quantum annealer with 5000+ qubits. First, we verified that accuracy generally increases with increasing annealing time. However, it is difficult to markedly increase the quantum annealing time due to strong quantum error. We also found that the accuracy of the quantum annealing measurement increases if the annealing pauses for some time and then begins again. Finally, the reversible adiabatic process enhances accuracy.
