Quantum Motion, a UK-based quantum computing scale-up, has announced a milestone in scalable quantum computing by demonstrating rapid, large-scale characterization of quantum devices fabricated using commercial semiconductor processes. The company designed a silicon chip featuring an integrated array of 1,024 quantum dots on an area of less than 0.1mm², validated in under five minutes—100 times faster than current methods. The chips were manufactured by GlobalFoundries, a leading semiconductor manufacturer, marking a strategic partnership to develop scalable silicon-based quantum processors.
The achievement, detailed in a peer-reviewed Nature Electronics paper, highlights the compatibility of quantum devices with high-volume semiconductor manufacturing. Quantum Motion’s chip, Bloomsbury, was fabricated on GlobalFoundries’ 22FDX® platform, leveraging its power-efficient edge processing and cryogenic tuning capabilities. This collaboration combines Quantum Motion’s quantum design expertise with GlobalFoundries’ advanced fabrication capabilities, paving the way for scalable quantum chip production.
Quantum Motion CEO James Palles-Dimmock emphasized the significance of using established semiconductor processes for quantum computing, while GlobalFoundries’ Ted Letavic highlighted the robustness of their 22FDX platform for enabling innovative quantum structures.
This breakthrough addresses key challenges in scaling quantum computing, integrating qubits and control electronics on a single chip. Quantum Motion plans to refine its designs and advance quantum-classical integration, moving closer to practical quantum processors.
