Entanglement transfer from light to atoms

We describe an approach to mapping of a quantum polarization state of free propagating light on a collective spin of an atomic ensemble. Recent experimental results on generation of a macroscopic spin squeezed ensemble of cold atoms via interaction with squeezed light are analysed in detail.
