Novel quantum refrigerator benefits from problematic noise

For quantum computers to function, they must be kept at extremely low temperatures. However, today's cooling systems also generate noise that interferes with the fragile quantum information they are meant to protect. Now, researchers at Chalmers University of Technology in Sweden have developed an entirely new type of quantum refrigerator, which is partly driven by the noise itself. This refrigerator enables very precise control over heat and energy flows and could play an important role in scaling up quantum technology.
