Sydney, Australia & Leuven, Belgium – October 2, 2025 – A groundbreaking achievement in quantum computing has sent ripples through the tech world, as a collaboration between UNSW Sydney nano-tech startup Diraq and European nanoelectronics institute imec announced a pivotal breakthrough on September 24, 2025. For the first time, industrially manufactured silicon quantum dot qubits have consistently demonstrated over 99% fidelity in two-qubit operations, a critical benchmark that signals a viable path toward scalable and fault-tolerant quantum computers.
This development is not merely an incremental improvement but a fundamental leap, directly addressing one of the most significant hurdles in quantum computing: the ability to produce high-quality quantum chips using established semiconductor manufacturing processes. By proving that high fidelity can be maintained outside of specialized lab environments and within commercial foundries on 300mm wafers, Diraq and imec have laid down a robust foundation for leveraging the trillion-dollar silicon industry to build the quantum machines of the future. This breakthrough significantly accelerates the timeline for practical quantum computing, moving it closer to a reality where its transformative power can be harnessed across various sectors.
Technical Deep Dive: Precision at Scale
The core of this monumental achievement lies in the successful demonstration of two-qubit gate fidelities exceeding 99% using silicon quantum dot qubits manufactured through industrial processes. This level of accuracy is paramount, as it surpasses the minimum threshold required for effective quantum error correction, a mechanism essential for mitigating the inherent fragility of quantum information and building robust quantum computers. Prior to this, achieving such high fidelity was largely confined to highly controlled laboratory settings, making the prospect of mass production seem distant.
What sets this breakthrough apart is its direct applicability to existing semiconductor manufacturing infrastructure. Diraq's qubit designs, fabricated at imec's advanced facilities, are compatible with the same processes used to produce conventional computer chips. This contrasts sharply with many other quantum computing architectures that rely on exotic materials or highly specialized fabrication techniques, which are often difficult and expensive to scale. The ability to utilize 300mm wafers – the standard in modern chip manufacturing – means that the quantum chips can be produced in high volumes, drastically reducing per-qubit costs and paving the way for processors with millions, potentially billions, of qubits.
Initial reactions from the quantum research community and industry experts have been overwhelmingly positive, bordering on euphoric. Dr. Michelle Simmons, a leading figure in quantum computing research, remarked, "This is the 'Holy Grail' for silicon quantum computing. It validates years of research and provides a clear roadmap for scaling. The implications for fault-tolerant quantum computing are profound." Experts highlight that by demonstrating industrial scalability and high fidelity simultaneously, Diraq and imec have effectively de-risked a major aspect of silicon-based quantum computer development, shifting the focus from fundamental material science to engineering challenges. This achievement also stands in contrast to other qubit modalities, such as superconducting qubits, which, while advanced, face different scaling challenges due to their larger physical size and complex cryogenic requirements.
