Abstract:
Atom interferometry is a rapidly developing field that has garnered significant attention in recent years due to its potential applications in fundamental physics research, including gravitational waves and dark matter, and in practical purposes such as sensing, metrology, and quantum computing. For example, point source atom interferometry (PSI) is a method developed to sense rotation in two axes and acceleration in the third. Here, we theoretically and numerically demonstrate how utilizing phase-space squeezing, namely, increasing the momentum of the atoms and effectively reducing the initial atomic cloud radius, improves the PSI device. Specifically, we detail how a squeezed PSI (SPSI) enhances sensitivity, expands dynamic range, and supports rapid cycling and high repetition rates. By identifying specific parameter regimes, we illustrate significant improvements in performance metrics by several orders of magnitude. Furthermore, we establish that SPSI offers superior compactness by more than four orders of magnitude under specific criteria. It is consequently suitable for scaling from traditional devices to compact chip-scale implementations, thus opening new avenues for practical applications.
