Abstract

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