The most notable advances this issue come from two directions: silicon-based quantum dots and superconductors. Diraq and imec’s 8-quantum-dot array achieved 99% fidelity on a standard CMOS process, further strengthening the scalability narrative for silicon spin qubits; meanwhile, Pan Jianwei’s team realized surface code logical gate operations on 107 qubits, marking a critical step for superconducting quantum computing from passive error-correcting storage toward active logical operations. In addition, QuTech released Tuna-17 and opened access via the cloud, lowering the barrier to superconducting quantum hardware. On the industry side, QuantumDiamonds’ large financing round and QIZ Security’s seed round reflect capital enthusiasm in quantum sensing and post-quantum cryptography, though one should be wary that some partnership announcements lack technical detail. Overall, hardware fidelity improvements and logical gate demonstrations are the core themes this week, and the pace at which quantum error correction moves toward practicality deserves continued attention.
