About C12 Quantum Electronics
C12 Quantum Electronics builds quantum computing hardware from carbon, using carbon nanotubes, which host spin qubits, rather than the superconducting circuits used by many rivals. Carbon nanotubes are hollow tubes of carbon about a nanometre wide. The company has described a nanoassembly process called Pick and Place for manufacturing nanotube quantum chips at larger scale. It has set out a roadmap toward fault-tolerant quantum computing, meaning machines that correct their own errors, which it has not yet demonstrated. Its address is in Paris, France, and it lists Thales as a collaborator on a radar tracking project.
C12 Quantum Electronics was founded in 2020 and is based in Paris, France. It is listed under Quantum Computing. Reported funding is €18M (~$19.4M) pre-Series A (2025).

What C12 Quantum Electronics works on
Quantum Computing
A quantum computer is a machine that uses the rules of quantum physics to process information. Its basic unit is the qubit. A classical bit is either 0 or 1. A qubit can be in a superposition, a state that combines both, and its measured result is probabilistic.
