C12 Quantum Electronics

C12 Quantum Electronics develops carbon-based quantum computing hardware using carbon nanotubes to create qubits with superior quality and connectivity. The company's unique approach avoids the scalability issues faced by other quantum computing architectures by leveraging better quality qubits and improved connection methods. C12 is advancing its Paris Project, aimed at driving one of the biggest technological breakthroughs of the century toward useful fault-tolerant quantum computing by 2033. Founded in 2019 and headquartered in Paris, France, the company has raised approximately $29.3M in Series A funding from investors including Bpifrance, EIC Fund, Airbus Ventures, BNP Paribas Developpement, and 360 Capital Partners. C12 differentiates itself by redefining the materials and architecture behind quantum hardware, using carbon for what silicon cannot deliver, with applications spanning chemicals, aerospace and defense, energy, and finance.
