Here, we use an optically levitated nanoparticle to measure impulsive forces smaller than the particle’s zero-point momentum uncertainty. Our approach relies on reversibly squeezing the levitated particle’s center-of-mass motion to coherently amplify the perturbation. We demonstrate an impulsive-force resolution as small as 6.9  keV/c, a value 0.6 dB below the sensor’s zero-point value.","lang":"eng"}],"researchdata_availability":"yes","oa":1,"month":"06","title":"Nanomechanical sensor resolving impulsive forces below its zero-point fluctuations","article_type":"original","date_published":"2026-06-12T00:00:00Z","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"date_updated":"2026-07-06T07:07:24Z"}]
