Boosting atomic signals by 1,000 times

In a new study, Northwestern University physicists have introduced a highly sensitive tool that amplifies incredibly faint signals by 1,000 times, marking a 50-fold improvement over previous capabilities. This tool, known as an atom interferometer, manipulates atoms with light to measure exceptionally tiny forces. What sets it apart from other atom interferometers is its ability to self-correct for imperfections in the light used, allowing it to achieve record-breaking levels of precision.
