Matthieu Desjardins C12 With Multi-Qubit Chips at Wafer Scale Building on the breakthrough of manufacturing quantum chips on 200mm silicon wafers using CMOS processes, C12 is pursuing the next materials leap in quantum computing: using carbon nanotubes to build quantum bits, or qubits, the fundamental building blocks of quantum computers. By combining an ultra-pure material with an easy-to-manufacture semiconductor device, the company is building a scalable and ultra-coherent platform for quantum computing. In addition, C12 and CEA have demonstrated a world-s-first ability to manufacture, with precision and in volume, core components to calibrate, control and read qubits, using standard manufacturing processes. Combined with C12-s unique nano-assembly process, this will enable large-scale integration of reliable qubits. In that process, nanotubes are assembled mechanically by C12 onto the semiconductor chip fabricated by CEA. This enables C12 to design electronic circuits with near-arbitrary complexity, while protecting the qubit from contamination until the final fabrication step. The two partners also have started manufacturing electronic chips for C12-s quantum accelerators, the startup's first product milestone.
