High-Temperature Superconductor Record at MIT

A research team at MIT published reproducible results in 2025 for a cuprate-based superconductor operating at minus 20 degrees Celsius under moderate pressure, a substantial advance toward practical superconductivity. While not yet room temperature, the discovery represented the highest confirmed superconducting temperature ever verified, with implications for lossless power grids and magnetic levitation technologies. The findings were replicated by three independent laboratories within six months.
