    "abstract": "The significance of the quantum feature of entanglement between physical\nsystems is investigated in the context of quantum measurements. It is shown\nthat, while there are measurement couplings that leave the object and probe\nsystems non-entangled, no information transfer from object to probe can take\nplace unless there is there is at least some intermittent period where the two\nsystems are entangled.
