A step closer to utility-scale quantum computing
In a landmark achievement, Imec (Belgium) and Diraq (Australia) have demonstrated that industrially fabricated silicon quantum dot qubits can consistently surpass the fidelity threshold required for quantum error correction. This breakthrough confirms the viability of CMOS-compatible fabrication processes for building reliable quantum systems at scale.
Over 99% two-qubit fidelity: from lab to foundry
Unlike traditional “hero” devices tested in academic labs, Diraq’s qubits were randomly selected from batches produced using Imec’s 300mm spin qubit platform. These qubits achieved over 99% fidelity in one- and two-qubit operations, and above 99.9% for state preparation and measurement (SPAM), all critical to real-world error correction.
Belgium’s industrial edge in the quantum race
Imec’s results signal that Europe’s semiconductor infrastructure is quantum-ready. This is not just a scientific milestone, but a commercial turning point that brings large-scale quantum computing closer to market, and cements Belgium’s role in the global quantum ecosystem.
