    "abstract": "We propose a measure of interaction-induced ground state entanglement in\nmany-fermion systems that is experimentally accessible. It is formulated in\nterms of cross-correlations of currents through resonant fermion levels weakly\ncoupled to the probed system. The proposed entanglement measure vanishes in the\nabsence of many-body interactions and it is related to measures of occupation\nnumber entanglement. We evaluate it for two examples of interacting electronic\nnanostructures.",
