C12, a French spin-off of the Physics Laboratory of the École Normale Supérieure in Paris which is developing a carbon nanotube-based universal quantum computer, has closed its second round at €18M. The new round of financing will allow C12 to accelerate its R&D work to create the first high-fidelity quantum operation on two distant spin qubits connected by a communication bus. C12 has also been selected for the Proqcima program, launched in March 2024 by the FrenchMinistry of the Armed Forces w...
