Finland – October 24, 2026 -- SemiQon, a 2023 spinout from Finland's VTT research institute, has shipped its first 4-qubit silicon spin-qubit chips to research collaborators after completing several fab runs. CEO and co-founder Himadri Majumdar says buyers should judge quantum processors on fidelity at scale and other system-level metrics, not on small-device fidelity alone.
