    "abstract": "Preparation of Schr\\\"odinger-cat-like states via conditional output\nmeasurement on a beam splitter is studied. In the scheme, a mode prepared in a\nsqueezed vacuum is mixed with a mode prepared in a Fock state and photocounting\nis performed in one of the output channels of the beam splitter. In this way\nthe mode in the other output channel is prepared in a Schr\\\"odinger-cat-like\nstate that is either a photon-subtracted or a photon-added Jacobi polynomial\nsqueezed vacuum state, depending upon the difference between the number of\nphotons in the input Fock state and the number of photons in the output Fock\nstate onto which it is projected. Two possible photocounting schemes are\nconsidered, and the problem of monitoring cats that are ``hidden\u0027\u0027 in a\nstatistical mixture of states is studied.",
