The applications of high efficiency quantum interrogation for the creation of entangled states of separate atoms and separate photons were presented. The quantum interrogation of a quantum object in a superposition of object-in and object-out left the object and probe in an entangled state. The entanglement was created without using prior entanglement states, and was tunable, while for the atoms the entanglement was achieved in situ, without bringing the atoms in proximity to each other.
