IBM engineers have completed the creation of a "superrefrigerator" for the next generation of quantum
Goldeneye contains 1.7 m3 of experimentalvolume. This is about three times the volume of an average refrigerator used in a home kitchen. At the same time, the temperature inside the device is lower than in outer space. The developers note that the previous generation of cooling devices for quantum computers were limited in size from 0.4 to 0.7 m3.

The developers have successfully cooled Goldeneye tooperating temperature of about 25 mK and launched a quantum processor (qubit chip) inside. The finished installation will be sent to the IBM Quantum Computing Center. Researchers will continue to study large-scale cryogenic systems to best meet the cooling needs of the quantum data centers of the future, the company says.
The company notes that the entire project tookonly three years. At the same time, Goldeneye features a completely new frame and cryostat design. In addition, it uses a modular design that simplifies prototyping, assembly and disassembly. The new model requires only four engineers, while previous installations required a team of at least ten specialists.
