中国科学技术大学研究团队首次证明真空中的量子涨落可以增强超导性1。研究人员将NbSe2超导材料置于特殊设计的太赫兹暗腔中，通过放大量子涨落实现了对超导体的非接触式控制，使得六层NbSe2器件的超导临界温度增加了5.4%1。这一成果表明超导增强效应在特定频率处出现共振峰，与暗腔的光子性质紧密相关1。
该研究由中国科学技术大学曾长淦教授团队主导，得到上海交通大学江清东教授和麻省理工学院Frank Wilczek教授等参与者的支持1。研究成果已发表在《自然》期刊2026年第657卷第8133期912-918页1。
Researchers at the University of Science and Technology of China have demonstrated that quantum fluctuations in vacuum can strengthen superconducting properties, marking a breakthrough in materials engineering.1 The team increased the critical temperature of a six-layer NbSe2 superconductor by up to 5.4% through a novel approach that harnesses these quantum effects.1
The study employed a terahertz split-ring resonator, known as a dark cavity, to amplify vacuum fluctuations and enhance the material's superconducting state without direct physical contact.1 This non-invasive method represents a new pathway for controlling quantum matter, with the superconducting enhancement effect exhibiting resonance peaks at specific frequencies that correlate closely with the cavity's photonic properties.1 The research, conducted at the University of Science and Technology of China and involving collaborators including Frank Wilczek, a professor at MIT who contributed to the theoretical framework, was published in Nature in 2026, volume 657, issue 8133, pages 912–918.1
