The talk highlighted why Si-based qubits are a leading candidate for scaling, leveraging mature semiconductor manufacturing and the prospect of co-integrating qubits with transistors to keep large quantum circuits comparable in footprint to classical processors.

Dr. Vinet presented FDSOI CMOS as a practical platform to co-integrate spin qubits with integrated control/read-out circuits, and shared recent advancements in quantum dot arrays, demonstrating elementary operations at microsecond timescales with state-of-the-art noise performance.

The session also covered FDSOI-based cryo-control electronics, demonstrating elementary control and read-out at cryogenic temperatures, and outlined strategies, as well as key challenges, for co-integrating qubits and integrated circuits at advanced technological nodes.

Participants left with a clearer view of how industry-compatible technologies can accelerate the engineering of “good qubits” and the roadmap to large-scale silicon quantum processors.
