Dual Open Atom Interferometry for Compact and Mobile Quantum Sensing Open
We demonstrate an atom interferometer measurement protocol compatible with operation on a dynamic platform. Our method employs two open interferometers, derived from the same atomic source, with different interrogation times to eliminate i…

Evaluation of a survey style quantum absolute gravimeter Open
We will present the status of the first survey style quantum absolute gravimeter developed at Nomad Atomics. We will report on the results of a comparison study between current state-of-the-art absolute gravimeters (FG5 and A10 Micro-g LaC…

Readout-delay-free Bragg atom interferometry using overlapped spatial fringes Open
A method for mitigating the readout delay characteristic of Bragg-based atom interferometry is presented, utilizing an asymmetric Mach-Zehnder interferometer sequence to generate spatial fringes that are read out while still overlapped. Th…

Mapping the absolute magnetic field and evaluating the quadratic Zeeman-effect-induced systematic error in an atom interferometer gravimeter Open
Precisely evaluating the systematic error induced by the quadratic Zeeman\neffect is important for developing atom interferometer gravimeters aiming at an\naccuracy in the regime ( ). This paper reports on the experimental\ninvestigation o…

Mobile quantum gravity sensor with unprecedented stability Open
Changes of surface gravity on Earth are of great interest in geodesy, earth sciences and natural resource exploration. They are indicative of Earth system's mass redistributions and vertical surface motion, and are usually measured with fa…
