摘要: Wave-particle duality finds a natural application for electrons or light propagating in disordered media where coherent corrections to transport are given by two-wave interference. For scatterers with internal degrees of freedom, these observed be much smaller than would expected structureless scatterers. By examining the basic example scattering one photon two spin-1/2 atoms---a case study backscattering---we demonstrate that loss interference strength is associated which-path information stored atoms.
