Founded in 2020 and based in the heart of Paris, C12’s mission is to be at the center of one of the greatest technological advances of the century and to change the course of history by building a universal quantum computer.

At C12, we believe that to achieve a true breakthrough in quantum computing, we need to rethink the fundamentals. That’s why our founders, deeply rooted in academic and technical excellence, chose carbon nanotubes as the building blocks for our quantum processors. This ultra-pure material significantly reduces error rates, improves performance, and minimizes hardware costs—all essential elements for scalable, fault-tolerant quantum computing. By developing a unique and scalable approach, we aim to revolutionize quantum computing, just as silicon transformed classical computing.

Since our inception, we have raised over €25 million in funding, published 11 scientific articles, and obtained 8 patents. Today, our rapidly expanding team includes 60 people, including 20 PhDs, representing over 20 nationalities. We have our own state-of-the-art laboratories in the historic Panthéon district of Paris, where scientists, engineers, and innovators work side by side to tackle some of the most exciting technical challenges of our time.

Founded in 2023, HiQuTe Diamond produces high-quality synthetic single-crystal diamonds using chemical vapor deposition (CVD).

We have expertise in growth on substrates with various orientations ({100} and {111}), controlled doping (particularly boron and nitrogen), and advanced treatment and characterization processes (Raman spectroscopy, DiamondView, defect imaging, stress measurement, etc.).

Our materials meet the requirements of emerging technologies: NV qubits for quantum computing and sensing, ultra-high voltage power electronics, and next-generation scientific sensors and instruments. Based in France, HiQuTe Diamond integrates the entire value chain—from growth to finishing—to offer agile, tailor-made solutions and contribute to European technological sovereignty.

We are looking for young PhD graduates who are passionate about materials and physics to take on the challenges that will accelerate the adoption of diamond in technology sectors.

We enable a 1,000-fold increase in the number of qubits in current infrastructures, thanks to cutting-edge cabling solutions for semiconductor quantum computers.

Silent Waves is a startup that markets quantum technologies. It specializes in the development and manufacture of ultra-low noise superconducting amplifiers, which amplify extremely weak signals generated at very low temperatures.

These amplifiers enable high-fidelity reading of superconducting quantum bits, a critical step in performing reliable quantum computing operations. Silent Waves’ technology roadmap aims to miniaturize the entire readout chain of superconducting quantum computers so that their architecture can be scaled up and integrate a very large number of quantum bits, which is essential for the development of quantum computing. The miniaturization of the readout chain involves, in particular, the integration on the circuit of microwave components that are peripheral to the amplifier but nevertheless essential to its operation. To achieve this goal, Silent Waves has won several competitions (Horizon Europe, i-Lab), as well as the prestigious EIC-Transition, which recognizes its key role in the maturation of quantum technologies.
