Atom interferometry, where quantum superposition is harnessed to perform high-precision measurements of physical quantities, has emerged as a versatile technique for both practical sensing applications and fundamental physics searches.
In this general-audience talk, we review the basics of atom interferometry and its main application areas.
We discuss some of the current main challenges towards the realisation of long-baseline atom-interferometry-based detectors for high-energy physics searches, and present ongoing work aimed at enabling large momentum transfer interferometry.
