From measurements performed on a low-noise two-stage SQUID amplifier coupled to a high-Q electrical resonator we give a complete noise characterization of the SQUID amplifier around the resonator frequency of 11 kHz in terms of additive, back action and cross-correlation noise spectral densities. The minimum noise temperature evaluated at 135 mK is 10 ¼K and corresponds to an energy resolution of 18 hbar

Abstract
From measurements performed on a low-noise two-stage SQUID amplifier coupled to a high-Q electrical resonator we give a complete noise characterization of the SQUID amplifier around the resonator frequency of 11 kHz in terms of additive, back action and cross-correlation noise spectral densities. The minimum noise temperature evaluated at 135 mK is 10 ¼K and corresponds to an energy resolution of 18 hbarFile in questo prodotto:
