Many-body coherence and entanglement probed by randomized correlation measurements

Abstract: We show how coherences between identical constituents of a many-body quantum state can be interrogated by suitable correlation functions and identify sufficient conditions under which low-order correlators fully characterize many-body coherences, as controlled by the constituents' mutual distinguishability. The comparison of correlators of different order detects many-body entanglement
