IBM Spins Off the First Pure-Play Quantum Chip Foundry

5 hours ago

IBM's Anderon foundry is designated as the centerpiece of the U.S. quantum industrial policy, backed by $2 billion in CHIPS funding, with $1 billion allocated to IBM's 300mm superconducting silicon facility.
The CHIPS quantum package includes significant investments in nine companies, creating a two-tier ecosystem: large-scale manufacturing for superconducting qubits and smaller equity stakes for competing modalities like trapped ion, photonic, and neutral atom.
300mm wafer fabrication offers a 30-fold increase in iteration speed over 200mm alternatives, leveraging existing semiconductor infrastructure to accelerate development of superconducting quantum systems.
The competition between superconducting silicon and trapped-ion approaches is framed as a manufacturing scalability issue, with superconducting qubits benefiting from established semiconductor production processes.
IBM is developing four custom ASICs (decoder, two-qubit gate controller, single-qubit controller, amplifier) to enable scalable fault-tolerant quantum systems by 2029, addressing classical control bottlenecks.
The U.S. government will take minority equity stakes in all nine quantum companies, extending a strategic investment model previously applied to other industries like semiconductors and rare earths.
Key areas to monitor include whether alternative modalities can secure manufacturing funding, the development of GlobalFoundries' quantum business, and the impact of government equity on company governance.
