C12 is leading the next materials leap in quantum computing

C12 is on a mission to build reliable quantum computers to speed up highly complex computing tasks, thanks to a unique technology developed at CNRS and the Physics Laboratory of the Ecole Normale Supérieure in Paris. In January 2020, twin brothers Matthieu and Pierre Desjardins officially launched the company.

C12 believes that only a materials science breakthrough will enable large-scale quantum computers. Unlike other quantum computers, we use carbon nanotubes as the fundamental building block of our processor. By combining the power of an ultra-pure material with an easy-to-manufacture semiconductor device, we are building the next generation of quantum computers, designed to provide unparalleled fidelity, connectivity, and scalability.

Our first product will be a quantum accelerator able to run hybrid quantum-classical algorithms for chemistry and optimization applications.

Silicon enabled the emergence of classical computing – it’s time for carbon to do the same for quantum!

C12 & Teratec

C12 wishes to actively participate in the Teratec ecosystem, whether through interventions or through some of its French and European partners already members of Teratec or carriers of innovative infrastructure projects in the field of quantum computing.
