Tunable superconducting two-chip lumped element resonator
Benedikt Ferdinand, Daniel Bothner, Reinhold Kleiner +1
We have fabricated and investigated a stacked two-chip device, consisting of a lumped element resonator on one chip, which is side-coupled to a coplanar waveguide transmission line…
Improving superconducting resonators in magnetic fields by reduced field-focussing and engineered flux screening
Daniel Bothner, Dominik Wiedmaier, Benedikt Ferdinand +2
We experimentally investigate superconducting coplanar waveguide resonators in external magnetic fields and present two strategies to reduce field-induced dissipation channels and…
Inductively coupled superconducting half wavelength resonators as persistent current traps for ultracold atoms
Daniel Bothner, Martin Knufinke, Helge Hattermann +7
A crucial point in the experimental implementation of hybrid quantum systems consisting of superconducting circuits and atomic ensembles is bringing the two partners close enough t…
