Reconfigurable SQUID Arrays

ORAL

Abstract

Superconducting quantum interference devices (SQUID) are widely used for sensitive magnetic field detection. Traditional SQUID arrays based on Superconductor/Insulator junctions have limited flexibility as junction properties are not tunable. The realization of Superconductor/Semiconductor junctions allows for gate-tunable junction properties. This allows for complex tunable SQUID arrays that can be continuously adjusted with voltage gates. We numerically study tunable SQUID arrays with various circuit geometries. Potential applications of these arrays include increased sensitivity to spatial inhomogeneity of fields and variable spatial resolution. Another potential advantage that is numerically explored is leveraging time dependent gate voltages to filter noise and increase sensitivity.
