Granular Aluminum Parametric Amplifier for Low-Noise Measurements in Tesla Fields
Nicolas Zapata, Ivan Takmakov, Simon Günzler +8
Josephson junction parametric amplifiers have become essential tools for microwave quantum circuit readout with minimal added noise. Even after improving at an impressive rate in t…
Observation of Josephson Harmonics in Tunnel Junctions
Dennis Willsch, Dennis Rieger, Patrick Winkel +27
Approaches to developing large-scale superconducting quantum processors must cope with the numerous microscopic degrees of freedom that are ubiquitous in solid-state devices. State…
Fano Interference in Microwave Resonator Measurements
D. Rieger, S. Günzler, M. Spiecker +3
Resonator measurements are a simple but powerful tool to characterize a material's microwave response. The losses of a resonant mode are quantified by its internal quality factor $…
Two-level system hyperpolarization using a quantum Szilard engine
Martin Spiecker, Patrick Paluch, Nicolas Gosling +16
The innate complexity of solid state physics exposes superconducting quantum circuits to interactions with uncontrolled degrees of freedom degrading their coherence. By using a sim…
Gralmonium: Granular Aluminum Nano-Junction Fluxonium Qubit
D. Rieger, S. Günzler, M. Spiecker +7
Mesoscopic Josephson junctions (JJs), consisting of overlapping superconducting electrodes separated by a nanometer thin oxide layer, provide a precious source of nonlinearity for…
