Dancing Nanoparticles and Quantum Limits

More recently, the field of levitated optomechanics, which deals with the control of high-mass micron-scale objects in vacuum, aims to push the envelope further by testing the validity of quantum phenomena in objects that are several orders of magnitude heavier than atoms and molecules. However, as the mass and size of an object increase, the interactions which result in delicate quantum features, such as entanglement, get lost to the environment, resulting in the classical behaviour we observe.
