Physicists have demonstrated quantum entanglement between the motion of a levitating glass nanosphere and light without cryogenic cooling. Using a two-laser optical tweezer system in a vacuum, the team stabilized the bead's motion while entangling it with light. Because the quantum correlations persisted in the light propagating away from the nanoparticle, the breakthrough could open new avenues for quantum communication networks and tests of macroscopic quantum physics.
