This tiny gold crystal could bring quantum technology out of the deep freeze

Physicists at LSU have created the first room-temperature quantum material capable of identifying and transporting quantum states of light. This breakthrough overcomes the traditional need for expensive cryogenic cooling systems, potentially enabling practical quantum technology in real-world devices.
Quantum materials could reshape fields as varied as high-performance computing, secure communication, sensitive detection, and energy production. Yet one persistent limitation has kept most of them from becoming practical technologies.
