Italian scientists transform light into a solid state

Researchers at Italy's National Research Council have, for the first time, transformed light into a solid state, which is a groundbreaking advancement in quantum physics.

This achievement reveals a unique form of matter that behaves both as a rigid structure and with fluidity, enriching our understanding of exotic quantum states.

Building on earlier experiments that demonstrated light's fluid behavior, the team's latest work culminates in the creation of a quantum supersolid, a state previously thought to exist only at ultralow temperatures.
