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…
