    "abstract": "We study the characteristics of the quantum state of light produced by a\nconditional preparation protocol totally performed in the continuous variable\nregime. It relies on conditional measurements on quantum intensity correlated\nbright twin beams emitted by a non-degenerate OPO above threshold. Analytical\nexpressions as well as computer simulations of the selected state properties\nand preparation efficiency are developed and show that a sub-Poissonian state\ncan be produced by this technique. Projection onto a given trigger value is\nstudied and then extended to a finite band. The continuous variable regime\noffers the unique possibility to improve dramatically the preparation\nefficiency by choosing multiple selection bands and thus to generate a great\nnumber of sub-Poissonian states in parallel.",
