Abstract
We show that when photons in -particle path-entangled or states undergo Bloch oscillations, they exhibit a periodic transition between spatially bunched and antibunched states. The period of the bunching-antibunching oscillation is times faster than the period of the oscillation of the photon density, manifesting the unique coherence properties of states. The transition occurs even when the photons are well separated in space.
