Microwave impedance readout of a hafnium microbridge detector
A. V. Merenkov, V. I. Chichkov, A. B. Ermakov +2
We present proof-of-operation for a new method of electron thermometry using microwave impedance of a hafnium micro-absorber. The new method leads to an ultimate THz-range detector…
Mode Structure in Superconducting Metamaterial Transmission Line Resonators
H. Wang, A. P. Zhuravel, S. Indrajeet +8
Superconducting metamaterials are a promising resource for quantum information science. In the context of circuit QED, they provide a means to engineer on-chip, novel dispersion re…
Interplay between kinetic inductance, non-linearity and quasiparticle dynamics in granular aluminum MKIDs
Francesco Valenti, Fábio Henriques, Gianluigi Catelani +13
Microwave kinetic inductance detectors (MKIDs) are thin film, cryogenic, superconducting resonators. Incident Cooper pair-breaking radiation increases their kinetic inductance, the…
Imaging collective behavior in an rf-SQUID metamaterial tuned by DC and RF magnetic fields
Alexander P. Zhuravel, Seokjin Bae, Alexander V. Lukashenko +3
We examine the collective behavior of two-dimensional nonlinear superconducting metamaterials using a non-contact spatially resolved imaging technique. The metamaterial is made up…
Probing the Tavis-Cummings level splitting with intermediate-scale superconducting circuits
Ping Yang, Jan David Brehm, Juha Leppäkangas +7
We demonstrate the local control of up to eight two-level systems interacting strongly with a microwave cavity. Following calibration, the frequency of each individual two-level sy…
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…
