Chinese researchers have achieved a landmark advancement in high-temperature superconductivity, unveiling two novel nickel-based materials that operate under ambient pressure. Published in Nature on Wednesday, the study led by Xue Qikun’s team at the Southern University of Science and Technology marks a critical step toward practical applications in energy transmission and quantum computing.
The breakthrough addresses a decades-old challenge in condensed matter physics: stabilizing materials that exhibit zero electrical resistance at higher temperatures. Nickel-based superconductors, a promising alternative to copper- and iron-based systems, have historically struggled with unstable oxidation states during synthesis. By deploying a novel strong oxidation atomic-layer epitaxy technique, scientists achieved precise atomic-scale control, enabling tailored superconducting films with transition temperatures up to 63 kelvin—a 40% improvement over prior results.
This innovation not only enhances energy efficiency but also opens pathways for next-gen technologies. Quantum sensors, lossless power grids, and advanced computing systems could benefit from these materials, which minimize energy waste. Collaborators from the University of Science and Technology of China emphasized the method’s scalability, suggesting industrial adoption may accelerate within this decade.
As global demand for sustainable energy solutions grows, this research positions the Chinese mainland at the forefront of materials science. With further optimization, nickel-based superconductors could redefine infrastructure across Asia and beyond, aligning with 2026’s push for climate-conscious technological leaps.
