C12 Quantum Electronics is a Paris-based quantum computing startup founded in 2020 as a spinoff from École Normale Supérieure that develops quantum processors using ultra-pure carbon nanotubes as qubits, leveraging isotopically purified 12C carbon atoms with zero nuclear spin to minimize decoherence and achieve near-ideal qubit performance, with €18 million in funding and an underground quantum fabrication facility in Paris producing quantum processors for cloud availability by 2025 and chip sales starting in 2026.
