    "abstract": "We discuss the possibility of generating and detecting, by a tomographic\nreconstruction of the Wigner function, a macroscopic superposition of two\ncoherent states. The superposition state is created using a conditioned\nmeasurement on the polarisation of a probe photon entangled to a coherent\nstate. The entanglement is obtained using a Kerr cell inserted in a Mach-Zender\ninterferometer. Some hint about generation of GHZ states is given as well.",
