Important results from the project
Yes, all project goals were successfully met. We developed and validated a proof-of-concept for next-generation control electronics for quantum computers, operating in a much wider frequency band (8-32 GHz). This technology is a key enabler for building more sustainable and scalable quantum computers. A high-frequency cryogenic testbed was established at KTH, which will enable future quantum research in Sweden.
Expected long term effects
The project lays the foundation for more powerful, scalable, and sustainable quantum computers. It will enable next-generation commercial control systems from IMP, strengthening Sweden´s quantum ecosystem. By allowing operation at higher temperatures and with more bandwidth, the technology will also reduce the energy footprint of future quantum computers, solidifying Sweden´s role as a leader in green quantum technology.
Approach and implementation
The project was structured as a collaboration between IMP, developing the electronics, and KTH, providing the quantum testbed. This setup worked very well. The project developed as planned, achieving all goals. However, the timeline was impacted by external factors; significant delays in the delivery of state-of-the-art converter chips, which are very new and difficult to procure, extended the project timeline. Despite this, the collaboration was highly effective and successful.
