The experimental apparatus is mounted inside a special refrigerator capable of reaching temperatures 1/100th of a degree above absolute zero.

Researchers at Princeton University turned light into crystals– essentially creating “solid light.” An assembly of 100 billion atoms of superconducting material, creating a sort of “artificial atom,” was placed near a superconducting wire containing photons. This arrangement artificially created a very strong interaction among the photons through quantum entanglement, leading to a new collective behavior of light akin to that of condensed matter.
