Important results from the project
The project advanced the technology for quantum-limited amplifiers (TWPAs) from research stage to commercial products. The QET Vidar TWPA has been industrialized and sold to international customers. A corresponding control electronics unit, the QET Mimir TWPA Controller, has been developed to a functional prototype. The project also strengthened collaboration between Chalmers and QET Sweden and contributed to patents, a doctoral thesis, and new international networks.
Expected long term effects
The project is expected to strengthen Sweden’s position in quantum technology by establishing a commercial platform for quantum-limited amplifiers. The results contribute to building a domestic value chain from research to industrial production and export. In the long term, the project is expected to create new jobs, promote international collaborations, and enable technological breakthroughs supporting the development of future quantum computers.
Approach and implementation
The project followed the planned structure and the chosen activities proved well selected. Collaboration between Chalmers and QET Sweden worked very well, resulting in rapid knowledge transfer and clear outcomes. The schedule was extended due to staff changes at Chalmers and technical challenges in the design, which led to deeper understanding and a more robust product. The project was successfully completed with all objectives achieved.
