The techniques of optical trapping and manipulation have already led to multiple Nobel prizes, with one of its most exciting development recently occurring in levitated optomechanics. A nano-sized object is optically trapped and manipulated using control theory techniques, offering industrial and medical applications, as well as an experimentally accessible platform for the future quantum technology sector.
