    "abstract": "We address the question whether identical-particle entanglement is a useful\nresource for quantum information processing. We answer this question positively\nby reporting a scheme to create entanglement using semiconductor quantum wells.\nThe Pauli exclusion principle forces quantum correlations between the spins of\ntwo independent fermions in the conduction band. Selective electron-hole\nrecombination then transfers this entanglement to the polarization of emitted\nphotons, which can subsequently be used for quantum information tasks.",
