Query: Optimal sub-Poissonian light generation from twin beams by photon-number
  resolving detectors   We generate nonclassical conditional states by exploiting the quantum
correlations of multi-mode twin-beam states endowed with a sizeable number of
photons. A strong relation between the sub-shot-noise correlations exhibited by
twin beams and the sub-Poissonian character of the conditional states is
experimentally revealed. It determines optimal conditions for sub-Poissonian
light generation.
