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…

Amplitude and frequency sensing of microwave fields with a superconducting transmon qudit

Maximilian Kristen, Andre Schneider, Alexander Stehli +9

Experiments with superconducting circuits require careful calibration of the applied pulses and fields over a large frequency range. This remains an ongoing challenge as commercial…

Introducing coherent time control to cavity-magnon-polariton modes

Tim Wolz, Alexander Stehli, Andre Schneider +5

By connecting light to magnetism, cavity-magnon-polaritons (CMPs) can build links from quantum computation to spintronics. As a consequence, CMP-based information processing device…

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…

Control of the Coupling Strength and the Linewidth of a Cavity-Magnon Polariton

Isabella Boventer, Christine Dörflinger, Tim Wolz +4

The full coherent control of hybridized systems such as strongly coupled cavity photon-magnon states is a crucial step to enable future information processing technologies. Thus, i…

Magnons at low excitations: Observation of incoherent coupling to a bath of two-level-systems

Marco Pfirrmann, Isabella Boventer, Andre Schneider +4

Collective magnetic excitation modes, magnons, can be coherently coupled to microwave photons in the single excitation limit. This allows for access to quantum properties of magnon…
