Entangled neutral atoms for interferometry beyond the standard quantum limit (B01)

Subject Area Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
Term since 2016
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 274200144
 

Project Description

Atom interferometers belong to today's most precise sensors with broad applications for navigation, geodesy, time keeping as well as fundamental research. Typically, they are operated with uncorrelated particles, resulting in a fundamental limitation of the achievable sensitivity. This sensitivity limitation can only be overcome by operating the interferometers with entangled particles. In this project, we advance our entanglement-enhanced interferometers from demonstration experiments to a valuable source for a future generation of highest-sensitivity atomic sensors.
