    "summary": "Heating silicon-nitride membranes in ultrahigh vacuum cut the dominant surface loss and pushed intrinsic coherence sharply upward.",
    "body_text": "Researchers report that annealing silicon-nitride membrane resonators at 1,000 degrees Celsius increased intrinsic quality factor by as much as twentyfold, reduced surface loss eightfold and increased tensile stress. Spectroscopy and in-situ surface analysis linked the change to silanol groups condensing into siloxane bridges; controlled humidity reversed both quality factor and stress, supporting a surface-chemistry mechanism. These are author-reported preprint results on laboratory resonators, not a demonstrated commercial quantum device.",
