Abstract: This study explores how variations in research topics impact the evolution of technologies, focusing on quantum technologies such as optics, metrology, imaging, and sensing. It finds that older fields, like quantum optics (established in 1958), exhibit lower topic diversity (entropy: 0.827) and are more concentrated on specific research areas (standard deviation: 4,330.3). In contrast, newer fields like quantum sensing (since 2000) show greater diversity (entropy: 0.925), suggesting a broader range of potential evolutionary paths (standard deviation: 49.6). Analysis reveals that quantum optics tends to focus on established topics, while quantum sensing explores emerging areas. Furthermore, 91.7% of topic variation occurs within fields, and statistical tests (ANOVA with F-test = 18.29, p-value = 0.001) confirm significant differences in topic distribution. The study suggests two key principles: 1) the diversity of research topics decreases as a field matures; 2) a field's inherent characteristics shape its technological trajectory, offering insights for better scientific forecasting and resource allocation.
