Florence Team Achieves Room-Temperature Entanglement Between Levitated Glass and Light
Researchers at the University of Florence have demonstrated persistent quantum entanglement between a levitated 100-nanometer glass nanosphere and light at room temperature. By using a dual-laser optical tweezer system, they cooled the sphere's motion to its quantum ground state while entangling it with outgoing light, bypassing the need for cryogenic cooling. This milestone, published in Science, provides a potential interface for quantum networks by allowing entangled states to travel via light.
