Abstract
We investigate the scattered field from identical two-level atoms resonantly driven by a weak coherent field in a one-dimensional waveguide. For atoms separated by the drive wavelength, increasing the number of atoms progressively suppresses transmission while enhancing photon bunching. Transmission becomes a superbunched -photon scattering process that is predominantly incoherent. Remarkably, we find that this transmission is only possible through a process where all atoms are excited, enabling heralded multi-photon state generation with applications in long-distance entanglement and quantum metrology.
