Direct identification of dilute surface spins on Al $_{2}$ O $_{3}$ : Origin of flux noise in quantum circuits

S. E. de Graaf, A. A. Adamyan, T. Lindström +4

It is universally accepted that noise and decoherence affecting the performance of superconducting quantum circuits are consistent with the presence of spurious two-level systems (…

Coupling of a locally implanted rare-earth ion ensemble to a superconducting micro-resonator

I. Wisby, S. E. de Graaf, R. Gwilliam +5

We demonstrate the coupling of rare-earth ions locally implanted in a substrate (Gd $^{3 +}$ in Al $_{2}$ O $_{3}$ ) to a superconducting NbN lumped-element micro-resonator. The hybrid d…

A near-field scanning microwave microscope based on a superconducting resonator for low power measurements

S. E. de Graaf, A. V. Danilov, A. Adamyan +1

We report on the design and performance of a cryogenic (300 mK) near-field scanning microwave microscope. It uses a microwave resonator as the near-field sensor, operating at a fre…
