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…
Rabi oscillations in a superconducting nanowire circuit
Yannick Schön, Jan Nicolas Voss, Micha Wildermuth +6
We investigate the circuit quantum electrodynamics of anharmonic superconducting nanowire oscillators. The sample circuit consists of a capacitively shunted nanowire with a width o…
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…
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…
Correlating decoherence in transmon qubits: Low frequency noise by single fluctuators
Steffen Schlör, Jürgen Lisenfeld, Clemens Müller +5
We report on long-term measurements of a highly coherent, non-tunable superconducting transmon qubit, revealing low-frequency burst noise in coherence times and qubit transition fr…
