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…

Fast superconducting qubit control with sub-harmonic drives
Mingkang Xia, Chao Zhou, Chenxu Liu +8
Increasing the fidelity of single-qubit gates requires a combination of faster pulses and increased qubit coherence. However, with resonant qubit drive via a capacitively coupled p…
