QST and NTT Develop Real-Time Fusion Plasma Communication
March 25, 2026
The National Institutes for Quantum Science and Technology (QST) and NTT, Inc. have jointly developed and demonstrated a groundbreaking fast frequent, real-time communication technology critical for fusion plasma prediction and control. This technology achieves data transfer cycles under 100 microseconds, enabling precise control of high-pressure plasma instabilities in fusion reactors such as the JT-60SA superconducting tokamak in Japan. This advancement supports ongoing fusion energy projects including ITER and DEMO, potentially accelerating fusion reactor operational capabilities.
- This innovation highlights opportunities for technology providers specializing in ultra-low latency communication systems and real-time control solutions within fusion energy research.
- Procurement professionals should note the collaboration between a federal research institute and a private technology firm, indicating potential for public-private partnerships in advanced scientific infrastructure.
- Organizations involved in fusion reactor development or plasma control systems may find increased demand for integrated communication technologies that meet stringent timing and reliability requirements.
- The demonstrated technology sets a precedent for future procurements related to fusion energy control systems, emphasizing the importance of cutting-edge communication capabilities in high-stakes scientific applications.
Fast frequent data communication at intervals shorter than 1/10,000 of a second previously unattainable with conventional technologies has been successfully achieved for the first time in the world.
