Researchers at Chalmers University of Technology and the University of Maryland have developed a record cold refrigerator that significantly improves the performance of quantum computers by cooling qubits to 22 millikelvins, enhancing reliability and reducing error rates. This autonomous refrigerator operates without constant external control, marking a significant advancement in quantum thermodynamics. However, researchers emphasize that further development is needed for quantum computers to reach their full potential in various applications. Teljes cikk (Euronews.com)
