  We discuss a general notion of quantum correlations in fermionic or bosonic
indistinguishable particles. Our approach is mainly based on the identification
of the algebra of single-particle observables, which allows us to devise an
activation protocol in which the \textit{quantumness of correlations} in the
system leads to a unavoidable creation of entanglement with the measurement
apparatus. Using the distillable entanglement, or the relative entropy of
entanglement, as entanglement measure, we show that our approach is equivalent
to the notion of minimal disturbance in a single-particle von Neumann
measurement, also leading to a geometrical approach for its quantification.
