According to Science and Technology Daily, the National Institute of Standards and Technology (NIST) of the United States and Chalmers University of Technology in Sweden have developed a new type of "quantum refrigerator" that can efficiently reset quantum bits and use the heat flow between the "refrigerator" components as a power source to maintain a low-temperature working environment. The results were published in the latest issue of Nature Physics, paving the way for the next step in developing reliable quantum computers.
