Ghost diffraction–interference fringes of bosons via ghost imaging

The time domain is a one-dimensional space, and hence the diffraction–interference in three dimensions is absent. However, ghost diffraction–interference (GD) building on a two-particle-enabled Young's experiment is still relevant. This is because fixed-timing detection can emulate pinhole detection at the core of GD. Here is demonstrated a different class of GD free of pinhole detection in the time domain. The bucket detection in ghost imaging enables it, which is best paraphrased as “ghost diffraction–interference via ghost imaging.”
