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…

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…

Tunable coherent microwave beam splitter and combiner at the single-photon level
Y. -H. Huang, K. -M. Hsieh, F. Aziz +10
A beam splitter is a key component used to direct and combine light paths in various optical and microwave systems. It plays a crucial role in devices like interferometers, such as…
