    "abstract": "We present some applications of high efficiency quantum interrogation\n(\"interaction free measurement\") for the creation of entangled states of\nseparate atoms and of separate photons. The quantum interrogation of a quantum\nobject in a superposition of object-in and object-out leaves the object and\nprobe in an entangled state. The probe can then be further entangled with other\nobjects in subsequent quantum interrogations. By then projecting out those\ncases were the probe is left in a particular final state, the quantum objects\ncan themselves be left in various entangled states. In this way we show how to\ngenerate two-, three-, and higher qubit entanglement between atoms and between\nphotons. The effect of finite efficiency for the quantum interrogation is\ndelineated for the various schemes.",
