    "abstract": "We construct a Hamiltonian for the generation of arbitrary pure states of the\nquantized electromagnetic field. The proposition is based upon the fact that a\nunitary transformation for the generation of number states has been already\nfound. The general unitary transformation here obtained, would allow the use of\nnonlinear interactions for the production of pure states. We discuss the\napplicability of this method by giving examples of generation of simple\nsuperposition states. We also compare our Hamiltonian with the one resulting\nfrom the interaction of trapped ions with two laser fields.",
