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…
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…
Transmon Qubit in a Magnetic Field: Evolution of Coherence and Transition Frequency
Andre Schneider, Tim Wolz, Marco Pfirrmann +4
We report on spectroscopic and time-domain measurements on a fixed-frequency concentric transmon qubit in an applied in-plane magnetic field to explore its limits of magnetic field…
An argon ion beam milling process for native layers enabling coherent superconducting contacts
Lukas Grünhaupt, Uwe von Lüpke, Daria Gusenkova +8
We present an argon ion beam milling process to remove the native oxide layer forming on aluminum thin films due to their exposure to atmosphere in between lithographic steps. Our…
Anisotropic rare-earth spin ensemble strongly coupled to a superconducting resonator
S. Probst, H. Rotzinger, S. Wünsch +5
Interfacing photonic and solid-state qubits within a hybrid quantum architecture offers a promising route towards large scale distributed quantum computing. Ideal candidates for co…
