Japan’s QST and NTT have achieved a world-first breakthrough in real-time communication technology for fusion energy, enabling ultra-fast data exchange needed to predict and control plasma in fusion reactors.
The system demonstrated communication cycles of under 100 microseconds—faster than 1/10,000 of a second—successfully implemented in the JT-60SA experimental reactor, the world’s largest superconducting tokamak.
The advance addresses a critical challenge in stabilizing plasma for fusion and is expected to support future large-scale projects such as ITER and next-generation reactors, marking a key step toward the practical realization of fusion energy.
