0,1,…,N: Exploring superconductor-semiconductor hybrids by adding Josephson junctions
This talk will highlight new opportunities for exploring superconductor-semiconductor hybrid systems, enabled by the revolutionary measurement capabilities of engineered superconducting circuits. Resonant circuits can probe the fragile superconductor-semiconductor interface , revealing behavior that is invisible to conventional probes. A single Josephson junction can be added to realize a semiconductor-based amplifier operating near quantum limits . Scaling up to junction arrays, I will present our most recent results on electrodynamics and radiometry of the anomalous metal.
