Quantum-limited amplification without instability
A. Metelmann, O. Lanes, T-Z. Chien +4
Quantum parametric amplifiers typically generate by operating in proximity to a point of dynamical instability. We consider an alternate general strategy where quantum-limited, lar…

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…
