Observation of directly interacting coherent two-level systems in a solid
Jürgen Lisenfeld, Grigorij J. Grabovskij, Clemens Müller +3
Parasitic two-level tunneling systems originating from structural material defects affect the functionality of various microfabricated devices by acting as a source of noise. In pa…
Quantitative evaluation of defect-models in superconducting phase qubits
J. H. Cole, C. Müller, P. Bushev +5
We use high-precision spectroscopy and detailed theoretical modelling to determine the form of the coupling between a superconducting phase qubit and a two-level defect. Fitting th…
In-situ measurement of the permittivity of helium using microwave NbN resonators
G. J. Grabovskij, L. J. Swenson, O. Buisson +3
By measuring the electrical transport properties of superconducting NbN quarter-wave resonators in direct contact with a helium bath, we have demonstrated a high-speed and spatiall…
