Intel has made significant advancements toward developing practical quantum computing by perfecting the scalability of silicon spin-based quantum processors. This progress could pave the way for fault-tolerant quantum computers, which are essential for real-world applications.

Intel has published new research indicating significant progress in the development of scalable, silicon-based quantum processors. Utilizing CMOS manufacturing techniques, similar to those used in traditional silicon chip production, Intel has demonstrated the potential for mass production of these quantum devices. Their research on 300-mm spin qubit wafers has shown remarkable uniformity and fidelity, achieving gate fidelities up to 99.9%. This advancement suggests that Intel's quantum processors could soon reach the scalability required for practical, fault-tolerant quantum computing. The ability to densely pack spin qubits, due to their small size, further supports the development of more complex quantum processors on a single chip, marking a significant step towards the integration of quantum computing into mainstream applications.
