Researchers of the Schliesser Lab at the Niels Bohr Institute, University of Copenhagen, have pushed the precision of force and position measurements into a new regime. Their experiment is the first to surpass the so-called 'Standard Quantum Limit,' or SQL, which arises in the most common (and successful) optical techniques for ultra-precise position measurements. The result and underlying experiment have potential implications for gravitational wave astronomy techniques, as well as force microscopy with biological applications.
