C12 plans its first logical qubit from carbon nanotube qubits in 2027

Due 2027

C12 says Aïdôs, the first of four processor generations on its roadmap, will arrive in 2027 and combine 16 physical carbon nanotube spin qubits into one logical qubit (an error-protected qubit) for its first logical operations.
