DESCRIPTION:LIGO gravitational wave detectors are among the most spectacul
 ar achievements of our civilisation in the field of precise measurements. 
 They are also an ideal platform to test cutting-edge ideas of quantum metr
 ology\, where non-classical properties of light are used to improve the se
 nsitivity of the devices. At the same time\, in recent years we have obser
 ved significant development in theoretical quantum metrology\, which combi
 nes fundamental ideas of quantum estimation theory with a quantum informat
 ion perspective on the optimisation of metrological protocols. This has ma
 de it possible to identify fundamental bounds on the precision of quantum-
 enhanced metrological devices that cannot be overcome\, no matter how soph
 isticated the quantum techniques applied are. Amazingly\, the performance 
 of present-day gravitational wave detectors comes close to these fundament
 al limits.\n\nhttps://indico.ific.uv.es/event/8864/
