On preparation of the atomic W-states

We analyse possibilities for quantum state engineering offered by the resonance Raman type interaction of light with ensembles of two-level atoms taking account relaxation to prepare and control of entangled states. It is found that atomic entanglement of the W-class can be obtained during evolution of atoms interacted with a single mode squeezed light. Two schemes, involving projection measurements that result in multipartite W-like states, are introduced.
