| Περίληψη: | We present a compact quantum gravimeter based on a grating magneto-optical trap using 87Rb atoms that achieves μ Gal-level long-term stability without passive vibration isolation. The sensor head integrates magnetic shielding, an ion pump, optical components, and a classical seismometer within a total volume of less than 75L. The gravimeter achieves a sensitivity of 270 μ Gal/ Hz and a stability of 5 μ Gal at a 1-h average with the long-term gravity record in good agreement with the theoretical tidal model. These results demonstrate a field-deployable platform for portable and chip-integrable quantum gravimetry. [ABSTRACT FROM AUTHOR] |
