About
Intel Quantum is Intel's quantum computing programme, which develops spin qubits made with the company's CMOS-industry manufacturing processes. In January 2026, Intel and Argonne National Laboratory deployed the 12-qubit Tunnel Falls quantum dot processor, a milestone published in Nature Communications that demonstrated CMOS-compatible quantum computing. In 2024, Intel's spin qubits achieved 99.9% gate fidelity, the highest reported for qubits made with all-CMOS-industry manufacturing, in research published in Nature under the title 'Probing single electrons across 300-mm spin qubit wafers.' On December 25, 2024, Intel published research on '12-Spin-Qubit Arrays Fabricated on a 300 mm Semiconductor Manufacturing Line' in Nano Letters. The Tunnel Falls device described there consists of 12 quantum dots arranged in a linear array, the largest number of qubits reported in a single Si/SiGe device to date. Intel researchers used a 300-millimeter cryogenic probing process, CMOS manufacturing techniques, and extreme ultraviolet (EUV) lithography to achieve tight dimensions while manufacturing in high volume. The small size of Intel's spin qubits, roughly 100 nanometers across, makes them denser than other qubit types such as superconducting qubits, which allows more complex quantum computers to be built on a single chip. Intel plans to demonstrate high-fidelity two-qubit gates on its industry manufacturing process and to develop 2D arrays with higher qubit count and connectivity.
