Detecting entanglement in many-body quantum systems is crucial butchallenging, typically requiring multiple measurements. Here, we establish theclass of states where measuring connected correlations in just $\textit{one}$basis is sufficient and necessary to detect bipartite separability, providedthe appropriate basis and observables are chosen. This methodology leveragesprior information about the state, which, although insufficient to reveal thecomplete state or its entanglement, enables our one basis approach to beeffective. We discuss the possibility of one observable entanglement detectionin a variety of systems, including those without conserved charges, such as theTransverse Ising model, reaching the appropriate basis via quantum quench. Thisprovides a much simpler pathway of detection than previous works. It also showsimproved sensitivity from Pearson Correlation detection techniques.
