A new window into the quantum realm has just been opened by a single microscopic grain of glass levitating in a beam of light.
In what may be the world's tiniest disco, physicists intertwined the grain's properties with those of light so tightly that one could not be described without including the other.
This is quantum entanglement – and this experiment marks the first demonstration of persistent entanglement between the motion of a levitated object and light that travels away from it, all without cryogenically cooling the apparatus.
It's a milestone that the researchers say could open new avenues for quantum communication and tests of quantum physics.
