Diraq

Diraq develops silicon quantum processors using CMOS-compatible fabrication processes to create quantum computers that leverage existing semiconductor manufacturing infrastructure, focusing on silicon-based spin qubits that can be manufactured using standard chip fabrication techniques to enable cost-effective scaling of quantum systems for practical applications.

November 2025: Selected for DARPA Stage B of Quantum Benchmarking Initiative (up to $15M funding) for silicon CMOS spin qubit technology, advancing toward utility-scale quantum computing by 2033.

In September 2025, Diraq and European nanoelectronics institute imec published breakthrough results in Nature demonstrating that silicon-based quantum chips can maintain world-class accuracy even when mass-produced in semiconductor foundries, achieving over 99% fidelity in two-qubit operations.

The research, published on September 24, 2025, showed that devices built on imec's 300mm spin qubit platform with isotopically enriched silicon demonstrated reproducible fidelities exceeding 99% for one- and two-qubit operations and above 99.9% for state preparation and measurement.

Unlike typical academic 'hero' devices, these results were obtained from randomly selected samples, confirming that scalable, high-fidelity silicon qubits can be produced using standard semiconductor manufacturing methods, marking a critical milestone for commercially viable quantum computing at scale.
