In the Cryo Quantum Lab at IFN-Trento we develop and investigate several types of ultrasensitive superconducting and micromechanical devices, with special interest in the application to quantum technologies and fundamental physics. We have available a large dry dilution refrigerator with base temperature 20 mK, equipped with microwave and SQUID instrumentation, a wet dilution refrigerator and several liquid helium cryostats.
