Abstract: Capturing specific kinds of quantum correlation is of paramount importance for quantum networking. Dif-ferent routes can be taken to achieve this task, highlighting different aspects of such quantum correlations. Following the recent theoretical results by Yadin, Fadel, and Gessner [Nat. Commun. 12, 2410 (2021)], we demonstrate experimentally how steering manifests in the metrological abilities of a bipartite state. Our results confirm the relevance of this approach, and compare the outcome with already employed alternatives.
