A small footprint travelling-wave parametric amplifier with a high Signal-to-Noise Ratio improvement in a wide band

Hampus Renberg Nilsson, Liangyu Chen, Giovanna Tancredi +6

We characterise a small footprint travelling-wave parametric amplifier (TWPA). The TWPA is built with magnetically flux-tunable superconducting nonlinear asymmetric inductive eleme…
