Physicists entangle levitating glass nanosphere with light at room temperature

As of October 2026: Lead institution of the experiment

A glass sphere about 100 nanometers wide, held aloft by laser light, has been quantum-entangled with the light that escapes its trap. The University of Florence team's result, published in Science on October 1, showed the sphere's motion and the outgoing light shared correlations that beat the limits any classical system could produce.
