By distinguishing between quantum systems suitable to act as reference frames and physical systems described relative to these frames, we define passive quantum reference frames and show that transformations between these cannot produce entanglement between physical systems. Our results also apply to the study of entanglement between subsystems in the perspectival framework even when there is no distinction between physical and reference systems.
