Macroscopically populated quantum superpositions pose a question to whatextent macroscopic world obeys quantum mechanical laws. Recently suchsuperpositions for light, generated by optimal quantum cloner, weredemonstrated. They are of fundamental and technological interest. We presentnumerical methods useful for modeling of these states. Their properties aregoverned by Gaussian hypergeometric function, which cannot be reduced toneither elementary nor easily tractable functions. We discuss the method ofefficient computation of this function for half integer parameters and moderatevalue of its argument. We show how to dynamically estimate a cutoff forinfinite sums involving this function performed over its parameters. Ouralgorithm exceeds double precision and is parallelizable. Depending on theexperimental parameters it chooses one of the several ways of summation toachieve the best efficiency. Methods presented here can be adjusted foranalysis of similar experimental schemes.
