Machine learning enables laser pulses to self-correct, reducing errors from flaws in the apparatus and improving overall precision.
Researchers at Northwestern University have developed a highly sensitive new tool that amplifies incredibly faint signals by 1,000 times, achieving a 50-fold improvement over previous methods.
The advancement could help in detecting subtle interactions of dark matter with ordinary matter, which have remained undetectable by even the most sensitive instruments.
The extremely accurate instrument, known as an atom interferometer, uses light to move atoms to measure incredibly small forces. However, the new instrument self-corrects for these flaws to achieve record-breaking precision, in contrast to other atom interferometers that are constrained by the faults in the light itself.
The team claims the technology can amplify imperceptible signals, aiding scientists in detecting ultra-weak forces from phenomena like dark matter, dark energy, and gravitational waves in new frequency ranges.
