Resonance fluorescence of an artificial atom with a time-delayed coherent feedback
Ching-Yeh Chen, Gavin Crowder, Zheng-Qi Niu +7
The model of light-matter interaction in quantum electrodynamics typically relies on the Markovian approximation, which assumes that the system's future evolution depends solely on…

Coherent transfer via parametric control of normal-mode splitting in a superconducting multimode resonator
Kai-I Chu, Xiao-Cheng Lu, Hsin Chang +5
Microwave storage and retrieval are essential capabilities for superconducting quantum circuits. Here, we demonstrate an on-chip multimode resonator in which strong parametric modu…

Tunable frequency conversion and comb generation with a superconducting artificial atom
Fahad Aziz, Zhengqi Niu, Tzu-Yen Hsieh +12
We investigate the power spectral density emitted by a superconducting artificial atom coupled to the end of a semi-infinite transmission line and driven by two continuous radio-fr…
