    "abstract": "Under some physical considerations, we present a universal formulation to\nstudy the possibility of localizing a quantum object in a given region without\ndisturbing its unknown internal state. When the interaction between the object\nand probe wave function takes place only once, we prove the necessary and\nsufficient condition that the object\u0027s presence can be detected in an initial\nstate preserving way. Meanwhile, a conditioned optimal interrogation\nprobability is obtained.",
