The technology is based on carbon nanotube wire suspended above a silicon chip containing a series of parallel wires that act as control electrodes and as a communication bus. The carbon nanotubes are composed of isotropically purified carbon-12 atoms – no carbon-14 – so they have zero nuclear spin, thus minimizing qubit decoherence.
The company was founded by twins Matthieu and Pierre Desjardins in January 2020, alongside Takis Kontos, a research director at CNRS, Matthieu Delbecq and Jérémie Viennot.
The money will be used to expand the workforce and establish a pilot production line, designed to include nanotube growth facilities, nano-assembly equipment, quantum measurement hardware, and more. Building upon the achievement of these first milestones, the startup aims to grow a range of quantum accelerators ready to be integrated into classical supercomputers, as well as design application-specific processors within the next five years.
The funds come from 360 Capital, Bpifrance, Airbus Ventures, BNP Paribas Développement, and Octave Klaba, with additional grants from Bpifrance and the Ile-de-France Region.
