SemiQon, a Finnish quantum technology startup, has raised €17.5 million ($18.3 million USD) in funding, including €15 million ($15.7 million USD) in equity and €2.5 million ($2.6 million USD) in grants from the European Innovation Council (EIC). The funding will support the development of its cryogenic CMOS technology, specifically for the Cool-CHIPS project, aiming to advance the technology from TRL6 to TRL8 within two years. This will enable product testing in customer environments, addressing strong demand for cryo-CMOS solutions in both quantum and classical computing markets.
The company, a spin-out from VTT Technical Research Centre of Finland, is also developing scalable, cost-effective silicon-based quantum processors. SemiQon’s cryo-CMOS technology includes a 64-channel on-chip multiplexer designed for quantum spin qubits, built on a custom silicon-on-insulator (SOI) process. The multiplexer operates at temperatures as low as 300mK, with minimal static power dissipation to avoid heating qubits, enabling scalable interfacing for large-scale quantum systems.
SemiQon’s approach leverages existing semiconductor infrastructure, reducing energy consumption and costs while supporting mass production. The company continues to focus on its long-term goal of enabling scalable quantum computing while diversifying into cryo-CMOS applications for faster commercial traction.
