Diraq and imec Demonstrate Eight-Qubit Linear Array Fabricated on 300 mm CMOS Silicon Foundries

Curator's Take

This article marks the first demonstration of an eight‑qubit linear array fabricated entirely on a commercial 300 mm CMOS silicon‑on‑insulator (SiMOS) platform, showing that high‑volume semiconductor foundries can produce quantum‑grade devices with performance comparable to research‑lab prototypes. By leveraging imec’s advanced nano‑electronics infrastructure, Diraq bridges the gap between bespoke qubit chips and scalable manufacturing pipelines, a step that aligns with recent progress from Intel and IBM on silicon spin qubits and could accelerate the transition to fault‑tolerant processors. The work also highlights remaining challenges—such as uniformity across larger arrays and integration of control electronics—but it provides a concrete proof‑of‑concept that silicon‑based quantum hardware can move toward mass production.
