Coupling Does Not Reduce the Auxiliary-Mode Count for Spectra in Passive Lindblad Networks
Qing-Ao Xiang, Yan Liu, Xin-Yuan Yang +1
Representing continuous environments by finitely many Markovian auxiliary modes is fundamental in non-Markovian open quantum systems, yet a critical question remains: at a fixed mo…
Phase-Selected Efficient Single-Photon Frequency Conversion via Local Fano Resonance in a Two-Giant-Atom Waveguide-QED System
Qing-Ao Xiang, Yan Liu, Xin-Yuan Yang +1
Efficient single-photon frequency conversion is investigated in a two-giant-atom waveguide-QED system, where a two-level giant atom and a -type three-level giant atom couple to…
On-Demand Control of Input-State-Dependent Single-Photon Scattering in Multi-Mode Waveguides
Yan Liu, Qing-Ao Xiang, Xin-Yuan Yang +4
Precise control of a single photon transport in broadband, multi-mode waveguides is a fundamental challenge for scalable quantum networks. We propose a theoretical scheme for on-de…
Controlling single-photon scattering in a rectangular waveguide by a V-type three-level emitter
Ya-Ju Song, Lei Qiao, Chang-Pu Sun
The single-photon scattering in a rectangular waveguide by a V-type three-level emitter is studied for large range of input-photon energy beyond the single-mode region. By using Li…
