Design of a Cooper pair box electrometer for application to solid-state and astroparticle physics
Leandro Tosi, Denis Vion, Hélène le Sueur
We describe the design and principle of operation of a fast and sensitive electrometer operated at millikelvin temperatures, which aims at replacing conventional semiconducting cha…
Inductive-detection electron-spin resonance spectroscopy with spins sensitivity
S. Probst, A. Bienfait, P. Campagne-Ibarcq +10
We report electron spin resonance spectroscopy measurements performed at millikelvin temperatures in a custom-built spectrometer comprising a superconducting micro-resonator at …
Quantum limited amplification from inelastic Cooper pair tunneling
S. Jebari, F. Blanchet, A. Grimm +7
Nature sets fundamental limits regarding how accurate the amplification of analog signals may be. For instance, a linear amplifier unavoidably adds some noise which amounts to half…
