The ‘quantum refrigerator’ can efficiently reset quantum bits, which helps reduce errors in the calculation process

On January 14th, the National Institute of Standards and Technology (NIST) in the United States collaborated with Chalmers University of Technology in Sweden to develop a new type of “quantum refrigerator” that can efficiently reset qubits and use the heat flow between “refrigerator” components as a power source to maintain a low-temperature working environment. This achievement was published in the latest issue of the journal Nature Physics, paving the way for the development of reliable quantum computers in the next step.
