This tiny gold crystal could bring quantum technology out of the deep freeze
Scientists have developed a room-temperature quantum material using a specially engineered gold film with microscopic structures, enabling the sorting and transport of different quantum states of light without requiring extreme cold. This breakthrough, published in Nature, could lead to more practical quantum technologies by eliminating the need for complex refrigeration systems. The material's design allows precise control over light interactions, opening possibilities for new applications in computing, communication, and sensing. The achievement represents a significant step toward making quantum materials viable for everyday use.
