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 qubits 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.
Our approach
Leverage existing semiconductor manufacturing capabilities
We bring quantum into industry
Real-world applications require thousands of logical qubits running on highly reliable machines. The only way to achieve this within the decade is to leverage existing semiconductor manufacturing.
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. This is 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.
3
1 and 2 qubits gates
1 qubits gates are obtained by applying magnetic field to electrons’spin.
2 qubits gates are obtained by lowering the barrier between the qubits.
4
Packaging
The die is packaged and connected to a PCB that is put into a cryostat at 1K. The fact that control electronics is within the chip allows for plug&play regular updates.
Technological, strategic
& industrial edge
Fast
Operating at 1MHz for physical operations, 10khz for logical ones
Reliable
With 70 years in semicon, we ensure reliability and aim for 75 to 85% disponibility rate
Scalable
Leveraging industry scaling—from 40 billion transistors to 1 million qubits on a single chip
