Summary
Eight silicon qubits were fabricated with a standard 300mm CMOS process, giving imec and Diraq evidence that quantum chips can be produced on conventional semiconductor lines rather than bespoke lab setups.
The advance builds on last year's one- and two-qubit results, showing the devices kept usable coherence even after scaling to eight qubits.
Researchers also said the jump to eight did not trigger a matching surge in control hardware such as wiring and sensors, a common bottleneck in other quantum architectures.
Eight qubits are far from a practical quantum computer, but the result points to a manufacturable path toward the thousands or millions of qubits large-scale systems are expected to need.
Quantum chips are now factory-made. When can businesses plug this power directly into their existing data centers?
As Diraq and Intel race to scale silicon qubits, who is poised to win the quantum manufacturing war?
How will mass-produced quantum chips redraw the map of global economic and military power?
Breaking Barriers: Eight Coherent Silicon Qubits on 300mm Wafer Mark Milestone for Scalable Quantum Chips
Overview
In mid-2026, Imec and Diraq achieved a major milestone by demonstrating the first coherent operation and readout of an eight-qubit silicon MOS spin-qubit array, fabricated using a 300mm CMOS-compatible foundry process. This breakthrough builds on Imec’s expertise in advanced semiconductor technologies and marks a crucial step toward integrating quantum computing with established industrial manufacturing. By leveraging standard chip production infrastructure, this achievement shows the potential for scalable quantum chip fabrication and paves the way for more robust, commercially viable quantum processors, aligning with Imec’s mission to bring lab innovations into real-world applications.
