International Researchers Create Room-Temperature Quantum State, Advancing Practical Quantum Technology
An international team of researchers has successfully engineered an exotic quantum state of matter that operates at room temperature, a significant departure from the extreme cooling typically required for such states. This breakthrough, detailed in Science Advances, involved creating a supersolid in an exciton-polariton Bose-Einstein condensate using a microcavity, a light-trapping structure. The setup is noted for its relative inexpensiveness and voltage controllability, capable of functioning at temperatures up to 60 °C (140 °F). This quantum state, which exhibits properties of both a superfluid and a solid with a crystal-like structure, was observed for fractions of a second, sufficient for the necessary observations. The research points towards more practical applications of quantum technology in advanced computing systems and sensors by simplifying the study of quantum behavior in superfluids and supersolids.
