C12 

C12 was founded in January 2020 by twin brothers Matthieu and Pierre Desjardins. Based in Paris, our technology is the fruit of ten years of research into the use of carbon nanotubes for quantum electronics at LPENS. Driven by a powerful ambition to develop the next-generation quantum computer to solve the world's most complex problems, we are the only startup to develop this kind of disruptive technology with carbon nanotubes. Backed by two rounds of financing - the latest of €18m in June 2024 - we have assembled a team of 45 talents, including 37 researchers and engineers and 18 different nationalities.

Qubit Pharmaceuticals 

Qubit Pharmaceuticals brings unparalleled accuracy and precision to drug discovery and design, using quantum physics to develop life-changing treatments for major diseases.

No target is undruggable.

Our proprietary technologies, the fruit of over 30 years of research, make it possible to develop novel drug candidates and innovative modes of action against targets previously considered too complex.
