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…
Slowing and Storing Microwaves in a Single Superconducting Fluxonium Artificial Atom
Ching-Yeh Chen, Shih-Wei Lin, Ching-Ping Lee +3
Three-level Lambda systems provide a versatile platform for quantum optical phenomena such as Electromagnetically Induced Transparency (EIT), slow light, and quantum memory. Such L…
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…
