A superconducting quantum circuit single artificial atom maser
Maria Mucci, Nicholas Hougland, Chun-Che Wang +4
We demonstrate a circuit QED analog of an atomic micromaser that utilizes an artificial, multi level atom, pumped into a population-inverted state by a microwave tone, as the gain…

Pump-efficient Josephson parametric amplifiers with high saturation power
Nicholas M. Hougland, Zhuan Li, Ryan Kaufman +4
Circuit QED based quantum information processing relies on low noise amplification for signal readout. In the realm of microwave superconducting circuits, this amplification is oft…
