Low temperatures suppress noise and make quantum phenomena accessible. As a result, cryogenics play a crucial role in precision measurements.

Almost all the devices developed by the Quantum Sensors Group work at temperatures below liquid helium. Sometimes, it is necessary to develop specialized cryogenics to test the devices, or to facilitate their dissemination to outside users.
The cryogenics team also aims to make refrigerators more accessible to cryogenic users through fundamental studies. For example, we are interested in the research and development of small and efficient compressors, methods for the rapid cooldown of cryostats, and the optimal utilization of available cooling power.
