Quantum radiation and metrology in the RF&MW regime

The sector develops circuit models and realizes wide-band parametric amplifiers in the microwave regime at the standard quantum limit for the multiplexing read-out of sensors and detectors of interest for fundamental physics.


The sector implements quantum radiation sources in microwaves for the realization of a heralded scheme aimed at the calibration of detectors with single photon sensitivity based on qubit networks (collaboration with the quantum optics sector) and for illumination based on quantum correlations (quantum radar).

The activity dedicated to the creation and characterization of a system for the measurement of scattering parameters in a cryogenic environment has recently been developed.
