NQFF and Qolab Collaborate on Wafer-Scale Cryogenic Filters for Quantum Scaling
Mohamed Abdel-Kareem2026-02-23T11:11:38-08:00The National Quantum Federated Foundry (NQFF) and Qolab have entered into a research collaboration to develop integrated cryogenic low-pass filters for quantum processors. The project aims to resolve hardware bottlenecks in scaling superconducting and spin-qubit systems by transitioning from discrete, bulky filter components to semiconductor-wafer-scale manufacturing. These filters are essential for shielding qubits from high-frequency microwave noise, which otherwise induces decoherence at millikelvin temperatures. The technical focus involves leveraging NQFF’s nanofabrication capabilities and Qolab’s systems expertise to produce filters directly on silicon wafers. This methodology allows for denser integration with qubit circuits and reduces the physical footprint within dilution refrigerators, facilitating [...]
