Generation of Glauber coherent state superpositions via unitary transformations

Abstract:
A unitary transformation mapping the vacuum state of an harmonic oscillator into a normalized superposition of two arbitrary Glauber coherent states is reported. Interesting features of the transformation are discussed. Generalizations to the superposition of N coherent states are considered.
