High-precision laser-based measurements face limitations from photon shot noise. The conventional solution to increase optical powers improves the signal-to-noise ratio, but can damage biological samples, affect mechanical devices with heat, necessitate extra laser safety measures, and have economic constraints. Squeezed light offers an alternative, reducing noise without power increase. \-\-\-\- Dieses Format wird im Rahmen des [EDIH Hamburg](https://edih-hamburg.de/), mit Unterstützung durch die Europäische Union und der Hamburgischen Investitions- und Förderbank angeboten. #EDIHHamburg
