Evaluation of IR-filters for scalable quantum computers

Important results from the project

The objective of the project was to develop a next-generation IR filter (HERD) for cryogenic, scalable quantum computers, with a focus on performance, scalability and stability. The objectives were essentially met: a new generation product was developed, and the concept was validated. The solution was anchored in the market through dialogue with international actors, which provided in-depth knowledge of the technology and customer needs.

Expected long term effects

In the longer term, the results could contribute to a new standard for filtering in scalable quantum computers. By enabling more compact filters, more signal lines can be handled when scaling up to systems with thousands of quantum bits. A strengthened market and network position shortens the path to industrialization and market introduction, and can strengthen Sweden´s position as a supplier of critical components for next-generation quantum technology.

Approach and implementation

The project was implemented in work packages: requirements analysis, product and prototype development, testing and verification, and commercial strategy and project management. The needs were validated in dialogue with customers and industry players, and the concept was validated through simulations and tests. The approach worked well and largely followed the schedule.
