Traditional electronics are not designed to perform at extreme temperatures. When it comes to space technologies, the challenge of chronically underperforming electronics has been widely recognized by the likes of NASA and DARPA (U.S. Department of Defense). So far, there has been no suitable solution in sight.

A significant new Business Finland funding accelerates the progress of Finnish quantum technology. A shared infrastructure environment is being built at the University of Jyväskylä's Nanoscience Center for researching and developing quantum technology platforms. The infrastructure will be open to both public and private research, and users will include university researchers as well as start-up companies. This is the only infrastructure in Finland that is openly available and focuses specifically on semiconductor-based quantum technologies. Shared infrastructures are still rarities internationally.
