Quantum entanglement and its use in metrology

We review various methods to verify the presence of quantum entanglement in
quantum systems. We also review recent findings showing that entanglement is
needed to beat the shot noise-limit thus outperforming classical
interferometry. We present concrete applications of the ideas above in
experiments with photons and cold atoms.
