Rydberg-dressing allows for the introduction of controllable long-range interactions for ground state atoms. In this work, we realize a Rydberg-dressed Ising spin system and study the interaction induced growth of spin-spin correlations in an interferometric measurement. This enables us to benchmark the predicted tunability of Rydberg-dressed interactions.
