| Description | We propose a feasible scheme for generation of strongly non-Gaussian states using the cross-Kerr nonlinearity. The resultant states are highly non-classical and exhibit negativity of their Wigner function, sub-Poissonian photon statistics and photon number squeezing. We show that creating and detecting such states should be possible with the present technology using electromagnetically induced transparency in a four-level atomic system. |
