➀ Imec and Diraq demonstrated silicon quantum dot qubits with error rates below the threshold for quantum error correction, achieving over 99% fidelity in one- and two-qubit gate operations;

➁ The qubits were fabricated using imec's industrial 300mm spin qubit platform and isotopically enriched silicon, ensuring low electrical/magnetic noise and high reproducibility;

➂ This collaboration validates a scalable, cost-effective semiconductor industry approach to mass-producing millions of qubits, a critical milestone for practical quantum computing.
