从理论预言到实验验证，从基础研究到应用突破，科研工作者以创新思维和严谨实证，不断推动拓扑材 料的研究、开发和应用。我很荣幸能和团队一起，在这项全球性的科学探索中贡献力量。 全球进入大科学时代，科学研究协同性显著增强。在拓扑电子材料的计算预测以及实验实现中，理论团 队刚开启外尔半金属预言研究时，实验团队便同步开始准备探测条件，包括调试"梦之线"光束线、搭建 实验装置等。样品制备团队及时根据理论与实验需求，不断优化材料制备工艺。这不是单向推进的过 程，而是多方向循环迭代的"正反馈"——实验中获取的材料性质数据，反馈给理论团队进行计算对比； 理论的进一步突破，又指导了实验方向调整；样品制备技术也会根据实验需求持续优化，进而为后续研 究提供更优质的样品。 如今，拓扑材料与拓扑量子计算研究仍在不断发展。我们希望继续为我国赢得国际话语权，更希望为相 关领域发展提供更多"中国方案"。未来，随着拓扑量子比特研发的突破，量子计算有望迎来新的发展阶 段。每一次科研突破，实际上都在为拓扑量子计算的未来铺路。这让我们更有信心、更有动力，为人类 科技文明的星河再添一抹亮色。 （作者为中国科学院院士、上海交通大学李政道研究所副所长，何旭 ...

Core Viewpoint - The research led by Professor Du Lingjie from Nanjing University has successfully captured the first image of a graviton, a significant breakthrough in the intersection of general relativity and quantum mechanics, which could unify these two fundamental theories of physics [1][2]. Group 1: Research Background - The graviton is theorized to exist in the context of quantum mechanics and general relativity, suggesting a potential unification of these theories, which would mark a new chapter in human civilization [1]. - Du's research focuses on "fractional quantum Hall gravitons" within condensed matter systems, where these gravitons may emerge as quasi-particles [1][2]. Group 2: Experimental Challenges - Du faced significant challenges in setting up experimental equipment after returning to China, including the need to maintain temperatures close to absolute zero for accurate measurements [2]. - The experimental setup required precise control of temperature, with a maximum deviation of 0.05°C from absolute zero, complicating the research process [2]. Group 3: Scientific Validation - Following the initial discovery, peer reviewers requested more definitive experimental evidence, prompting Du to design new experiments to measure smaller momentum excitations [3]. - At an international conference, Du presented new evidence from gallium arsenide quantum wells, addressing previous skepticism and gaining recognition from experts in the field [5]. Group 4: Future Directions - The research team, composed of young scholars with an average age of 25, is now focusing on a new quantum state, which could pave the way for advancements in topological quantum computing [5]. - Du emphasizes the importance of aiming for cutting-edge research to expand cognitive boundaries and drive breakthroughs in the field [5].
