We present a feasible proposal for the construction of the conditional displacement operator
using a Kerr medium between two beam splitters fed from coherent states
highly excited. The device allows the implementation of the generation of a new class of states
the quantized electromagnetic field (arbitrary superpositions of states with states
moved) and the measurement of the Wigner function for arbitrary states. The application
special case of the number of states and study their nonclassical properties were
also considered.
