Subradiance-protected excitation spreading in the generation of collimated photon emission from an atomic array
K. E. Ballantine, Janne Ruostekoski
Abstract
This paper show how a localized single photon excitation in a two dimensional array of cold atoms, which would emit in all directions, can be converted to a protected, delocalized subradiant one, which can then produce coherent collimated emission. This protected spreading and directional emission could be used to link stages in modular quantum architectures for quantum information processing.
