Three-terminal superconductor (S) - normal metal (N) - superconductor (S) Josephson junctions are investigated. In a geometry where a T-shaped normal metal (Cu) is connected to three superconducting reservoirs (Al), a sub-gap structure appears in the differential resistance for specific combinations of the superconductors chemical potentials. These features are consistent with the prediction of non-local quartets formed by correlated Cooper pairs and open perspectives toward a new generation of electronic entanglers.
