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…

Group delay controlled by the decoherence of a single artificial atom
Y. -T. Cheng, K. -M. Hsieh, B. -Y. Wu +12
The ability to slow down light at the single-photon level has applications in quantum information processing and other quantum technologies. We demonstrate two methods, both using…
