Abstract

The general concept of entangled photon holes is based on a correlated absence of photon pairs in an otherwise constant optical background. Here we consider the specialized case when this background is confined to two well-defined time bins, which allows the formation of time-bin-entangled photon holes. We show that when the typical coherent-state background is replaced by a true single-photon (Fock state) background, the basic time-bin-entangled photon-hole state becomes equivalent to one of the time-bin-entangled photon-pair states. We experimentally demonstrate these ideas using a parametric down-conversion photon-pair source, linear optics, and postselection to violate a Bell inequality with time-bin-entangled photon holes.
