With a base temperature of ~10 mK, the "Ieti" cryostat allows the simultaneous operation of qubits and cryogenic detectors.

It is located in the HallC of the INFN Laboratori Nazionali del Gran Sasso (L' Aquila, Italy). The 1.4 km rock overburden suppresses the muon flux and the neutron flux by a factor of 1 milion and 1000, respectively.  Moreover, the facility is heavily shielded against the laboratory natural radioactivity, offering the ideal environment to test devices in which low-radioactivity levels are required.

Today, the Ieti facility is being used by the SQMS (Superconducting Quantum Materials and Sytems) Center, the CUPID (CUORE Upgrade with Particle IDentification) experiment, as well as by R&D projects for the development of detectors to study supernovae neutrinos, and for high precision measurements of beta spectra.
