Superconducting microwave magnetometer for absolute flux detection
Simon Günzler, Patrick Winkel, Dennis Rieger +5
Superconducting quantum interference devices (SQUIDs) are among the most sensitive detectors for out-of-plane magnetic field components. However, due to their periodic response wit…
Tunable Anderson Localization of Dark States
Jan David Brehm, Paul Pöpperl, Alexander D. Mirlin +4
Random scattering of photons in disordered one-dimensional solids gives rise to an exponential suppression of transmission, which is known as Anderson localization. Here, we experi…
Quantum beats of a magnetic fluxon in a two-cell SQUID
I. N. Moskalenko, I. S. Besedin, S. S. Seidov +2
We report a detailed theoretical study of a coherent macroscopic quantum-mechanical phenomenon - quantum beats of a single magnetic fluxon trapped in a two-cell SQUID of high kinet…
Quantum Sensors for Microscopic Tunneling Systems
Alexander Bilmes, Serhii Volosheniuk, Jan D. Brehm +2
The anomalous low-temperature properties of glasses arise from intrinsic excitable entities, so-called tunneling Two-Level-Systems (TLS), whose microscopic nature has been baffling…
Coherent superconducting qubits from a subtractive junction fabrication process
Alexander Stehli, Jan David Brehm, Tim Wolz +6
Josephson tunnel junctions are the centerpiece of almost any superconducting electronic circuit, including qubits. Typically, the junctions for qubits are fabricated using shadow e…
Waveguide Bandgap Engineering with an Array of Superconducting Qubits
Jan David Brehm, Alexander N. Poddubny, Alexander Stehli +3
Waveguide quantum electrodynamics offers a wide range of possibilities to effectively engineer interactions between artificial atoms via a one-dimensional open waveguide. While the…
