Fabrication and characterization of low-loss Al/Si/Al parallel plate capacitors for superconducting quantum information applications

Abstract Increasing the density of superconducting circuits requires compact components, however, superconductor-based capacitors typically perform worse as dimensions are reduced due to loss at surfaces and interfaces. Here, parallel plate capacitors composed of aluminum-contacted, crystalline sili...
