We discuss a general notion of quantum correlations in fermionic or bosonicindistinguishable particles. Our approach is mainly based on the identificationof the algebra of single-particle observables, which allows us to devise anactivation protocol in which the \textit{quantumness of correlations} in thesystem leads to a unavoidable creation of entanglement with the measurementapparatus. Using the distillable entanglement, or the relative entropy ofentanglement, as entanglement measure, we show that our approach is equivalentto the notion of minimal disturbance in a single-particle von Neumannmeasurement, also leading to a geometrical approach for its quantification.
