Collection description
In this thesis it is presented a novel superconducting microwave circuit, the Gradiometric SNAIL, that is capable of synthesizing in-situ tunable Hamiltonians with two degrees of freedom. Such a feature allows more flexibility in the choice of linear and non-linear processes that allow coherent elaboration of weak microwave photons. The Gradiometric SNAIL has been employed to implement a resonant parametric amplifier that, with two tuning degrees of freedom, is capable to provide 20dB gain amplification with three-wave mixing over a broad range of operating frequencies and simultaneously suppress the parasitic Kerr effect.
