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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
