Abstract

We discuss how flux pumping can be applied to multiple inductively coupled superconducting circuits, and describe its importance to the operation of a novel, planar magnetic field source for quantum technology applications. Specifically, we discuss how applying a transformer-rectifier flux pumping technique to several double-loop superconducting structures simultaneously allows for the effect of cross-talk — the inevitable coupling between neighbouring superconducting loops — to be accounted for. Using both a theoretical model and an experimental verification, we introduce a method of calibrating a flux-pumped magnetic field source such that any desired magnetic field distribution within the critical current limits of the used materials can be obtained.
