Spins in semiconductor quantum dots constitute a promising platform for scalable quantum information processing. Coupling them strongly to the photonic modes of superconducting microwave resonators would enable fast non-demolition readout and long-range, on-chip connectivity, well beyond nearest-neighbour quantum interactions. Here we demonstrate strong coupling between a microwave photon in a superconducting resonator and a hole spin in a silicon-based double quantum dot issued from a foundry-compatible metal-oxide-semiconductor fabrication process.

- CMOS technology's advanced nanoscale integration is pivotal for spin-based quantum computing, showing promise in early quantum dot formation and spin blockade demonstrations.
- Although CMOS results are encouraging, they still lag behind the precise control of individual electrons seen in university-developed multigate designs.
- This study demonstrates how quantum dots in a CMOS nanowire can be effectively controlled using a remote single electron transistor (SET) through floating coupling gates, enabling the formation of a 2x2 quantum dot array and enhanced charge sensing.
