C12 Information

C12 is a Paris-based quantum computing startup building the next generation of scalable quantum computers. Unlike Big Tech players, we’re pioneering a unique approach rooted in breakthrough materials science and novel interconnects. It's widely seen as the only path to true large-scale quantum computing. We’re early-stage, fast-moving, and already a leader in Europe for spin qubits. Backed by over €25M in equity funding, our international team of 85 includes over 25 world-class quantum scientists. Together, we’ve built a first-of-its-kind quantum chip production line and delivered devices with record-setting performance. C12 is already generating revenue by partnering with leading industrial companies, helping them begin their quantum computing journey and tackle their most complex computational challenges.
