Influence of bias voltage noise on the Inelastic Cooper-Pair Tunneling Amplifier (ICTA)
Ulrich Martel, Romain Albert, Florian Blanchet +7
We experimentally show that the Inelastic Cooper-Pair Tunneling Amplifier (ICTA), implementing a DC-powered parametric amplification scheme, can achieve gain and noise performance…
