  We address the question whether identical-particle entanglement is a useful
resource for quantum information processing. We answer this question positively
by reporting a scheme to create entanglement using semiconductor quantum wells.
The Pauli exclusion principle forces quantum correlations between the spins of
two independent fermions in the conduction band. Selective electron-hole
recombination then transfers this entanglement to the polarization of emitted
photons, which can subsequently be used for quantum information tasks.
