ANALYSIS Science

An Inverted Optical Trap Squeezed a Nanoparticle’s Motion by 11 Decibels in 250 Nanoseconds

An ETH Zurich experiment rapidly reduced uncertainty in one component of a levitated particle’s angular motion. Technical noise and a short cavity-limited lifetime still constrain its use.
