Description
We present a general criterion for entanglement of N indistinguishable particles decomposed into arbitrary s subsystems based on the unambiguous measurability of correlation. Our argument provides a unified viewpoint on the entanglement of indistinguishable particles, which is still unsettled despite various proposals made mainly for the s=2 case. Even though entanglement is defined only with reference to the measurement setup, we find that the so-called independently and identically distributed states form a special class of bosonic states which are universally separable.
