In a groundbreaking discovery, researchers have found that certain disordered superconductors like indium oxide films experience sharp and sudden phase transitions. This revelation challenges conventional beliefs about how these transitions occur, with significant implications for the future of quantum computing technology.
The comprehensive study, published in the prestigious journal Nature, revealed that indium oxide films defy traditional expectations by shifting abruptly from a superconducting to an insulating state. This dramatic first-order transition is a stark contrast to the gradual, second-order transitions usually observed in superconductors.
