The next big thing of the silicon industry is the quantum chip
We are upgrading the SOI (Silicon On Insulator) into a QSOI® (Quantum Silicon on Insulator)
Building block after building block, FD-SOI-based silicon qubit demonstrations developed at CEA-Leti are transferred to STMicroelectronic’s 300mm manufacturing lines. Together with STMicroelectronics we ensure process control, yield optimization, and scalability.
Our industrial partner: STMicroelectronics
Our quantum chips are co-designed with STMicroelectronics and manufactured on its 300mm semiconductor platform.
This collaboration provides immediate access to industrial-grade manufacturing, ensuring robustness, reproducibility, and scalability.
Leveraging semiconductor manufacturing at scale
We industrialize quantum computing.
Real-world applications require thousands of reliable logical qubits. Anything less remains limited in scope. By leveraging the semiconductor industry and manufacturing ecosystem, we deliver scalable, cost-efficient, and industrial quantum systems.
1
Wafers
Usual FD-SOI’s wafers are made of silicium that are noisy in terms of spins. Purified wafers based on 28Si allow for a spin-free environment. These are our QSOI ® wafers.
2
Chips
Scaling quantum computing requires moving from the lab to the fab. While research facilities are great for prototyping and small scale demos, only industrial manufacturing lines guarantee the precision and reproducibility needed to build large-scale Fault-Tolerant Quantum Computers.

1- and 2-qubit gates
1-qubit gates are obtained by applying magnetic fields to an electron’s spin.
2-qubit gates are obtained by lowering the barrier between the qubits.
4
Packaging
The die is packaged and connected to a PCB that is lowered to a temperature of 1 K in a cryostat. The control electronics embedded within the chip enable regular plug&play updates.
