This paper investigates the impact of thermal fluctuations on quantum coherence and quantum correlations in graphene nanoribbons with Dzyaloshinskii–Moriya interaction. Using a model of narrow armchair graphene nanoribbons with zigzag ends, the study analyzes how temperature, nanoribbon length, and the Dzyaloshinskii–Moriya coupling parameter affect the \(l_1\) -norm of coherence and measurement-induced disturbance, which are key quantifiers of quantum properties. The results show that both quantum coherence and correlations decrease as temperature increases, indicating a progressive loss of quantum information. However, a stronger Dzyaloshinskii–Moriya interaction partially preserves these quantum features by enhancing coherence and correlations, particularly at low temperatures. Notably, quantum correlations decay faster than coherence, highlighting their greater sensitivity to thermal noise. These findings underscore the stabilizing role of the Dzyaloshinskii–Moriya interaction and provide insights for designing robust graphene-based quantum devices for applications in quantum computing and secure communication.
