Silicon Spin Quits Move From Access to Allocated Capacity

Foundry-backed silicon spin qubits are shifting quantum competition from lab access to scalable industrial capacity.

Updated

What is this trend?

Silicon spin qubits are moving from lab access to allocated manufacturing capacity, with foundry, cryogenic CMOS, and PDK support becoming the real competitive moat.

  • Imec and GlobalFoundries are turning silicon spin into backed industrial capacity, not just fab access.
  • Intel K.K. and Hitachi are standardizing the stack with a silicon spin-qubit PDK on Intel 18A.
  • The race is shifting to repeatable fabrication, cryogenic control, and packaging at scale.
  • Diraq’s roadmap points to 1,000+ qubits in 2025–2029 and million-qubit ambitions after 2029.
  • Vertical integration and domestic supply-chain control are becoming strategic responses across quantum hardware.

What’s the latest?

imec’s backing of a 300 mm CMOS path for Diraq’s silicon MOS spin qubits, plus GlobalFoundries’ CHIPS Act-backed cryogenic CMOS capacity, pushes silicon spin from manufacturing promise into allocated industrial infrastru

PQC procurement locks in, silicon spin scales, and verifiable fault tolerance becomes the benchmark
