SemiQon

SemiQon is a Finland-based company focused on silicon-based quantum hardware for quantum computing. Its stated mission is to support the scale-up of quantum computing with semiconductor-based hardware that addresses scalability, cost, and sustainability. The company says its technology includes cryo-optimized CMOS solutions, silicon quantum dot devices, and future silicon-based QPUs, and that its chips and control electronics are designed to operate at warmer temperatures than alternative approaches.

According to its about page, SemiQon was founded in 2023 and is headquartered in Finland, with operations based at the Micronova Center for Applied Micro and Nanotechnology in Espoo. The company describes itself as a spin-out from VTT and says it entered independent operations in early 2023.
