Enhancement of quantum excitation transport by photonic nonreciprocity
Enhancement of quantum excitation transport by photonic nonreciprocity
Enhanced interaction between two two-level emitters (e.g., atoms) by nonreciprocal photonic media can be of benefit to broad areas, from quantum information science to biological detection. Here we provide a detailed analysis on why nonreciprocal photon-mediated interaction enhances inter-atomic excitation transport efficiency. We investigate a system consisting of two two-level …
