GNSS-free quantum gravity-aided navigation and fine-scale marine surveying with a strapdown quantum gravimeter
Patrick J. Everitt, Donald H. White, Todd Lyon +19
Global navigation satellite systems (GNSS) are often disrupted or unavailable at sea, and unaided inertial navigation systems (INS) drift without correction. Quantum-sensing-based…

Enhanced squeezing for quantum gravimetry in a Bose-Einstein condensate with focussing
Lewis A. Williamson, Karandeep Gill, Andrew J. Groszek +2
Free-fall atom interferometers offer a powerful platform for accurate, absolute gravitational sensing. Szigeti et al. [Phys. Rev. Lett. 125, 100402 (2020)] recently proposed a quan…

Enhancing the sensitivity of atom-interferometric inertial sensors using robust control
J. C. Saywell, M. S. Carey, P. S. Light +13
Atom-interferometric quantum sensors could revolutionize navigation, civil engineering, and Earth observation. However, operation in real-world environments is challenging due to e…
