Granular aluminum: A superconducting material for high impedance quantum circuits
Lukas Grünhaupt, Martin Spiecker, Daria Gusenkova +8
Superconducting quantum information processing machines are predominantly based on microwave circuits with relatively low characteristic impedance, of about 100 Ohm, and small anha…
Circuit Quantum Electrodynamics of Granular Aluminum Resonators
N. Maleeva, L. Grünhaupt, T. Klein +12
The introduction of crystalline defects or dopants can give rise to so-called "dirty superconductors", characterized by reduced coherence length and quasiparticle mean free path. I…
Quasiparticle dynamics in granular aluminum close to the superconductor to insulator transition
Lukas Grünhaupt, Nataliya Maleeva, Sebastian T. Skacel +7
Superconducting high kinetic inductance elements constitute a valuable resource for quantum circuit design and millimeter-wave detection. Granular aluminum (GrAl) in the supercondu…
Local Sensing with the Multi-Level AC Stark Effect
Andre Schneider, Jochen Braumüller, Lingzhen Guo +5
Analyzing weak microwave signals in the GHz regime is a challenging task if the signal level is very low and the photon energy widely undefined. A superconducting qubit can detect…
