Description
Over the last 10 years, granular aluminium has risen as a popular material for implementation in superconducting circuits thanks to its high kinetic inductance, low loss with approachable fabrication.
Where granular aluminium really shines is as the nonlinear element for parametric amplification, showing both magnetic field resilience, robustness for multi pumping schemes with a compact footprint. In this talk we compare grAl to other disordered superconductors and junction arrays and show how its tuneable nonlinearity stands out.
