Core Insights - The Massachusetts Institute of Technology (MIT) physicists have observed key evidence of unconventional superconductivity in twisted trilayer graphene (MATTG), which is a significant step towards achieving room-temperature superconductivity [1][2] - Room-temperature superconductivity could enable technologies such as zero-energy transmission cables, efficient power grids, and practical quantum computing systems [1] - MATTG exhibits unique quantum properties due to its specific twisting angle, leading to the emergence of a new research field known as "twisted electronics" [1] Summary by Sections - **Unconventional Superconductivity**: The direct observation of superconducting energy gaps and zero-resistance characteristics in MATTG indicates that its electron pairing mechanism differs from traditional superconductors, suggesting a new superconducting mechanism [1][2] - **Experimental Methodology**: A newly developed experimental platform combined electron tunneling measurements with electrical transport tests, allowing simultaneous observation of superconducting energy gaps and zero-resistance states [1] - **Future Research Directions**: The research team plans to explore more twisted structures and materials using the new platform, aiming to uncover the nature of electron pairing and quantum state competition, which could lead to the design of new efficient superconductors and quantum computing materials [2]
