Numerical model for macroscopic quantum superpositions based on phase-covariant quantum cloning

Abstract Macroscopically populated quantum superpositions pose a question to what extent the macroscopic world obeys quantum mechanical laws. Recently, such superpositions for light, generated by an optimal quantum cloner, have been demonstrated. They are of fundamental and technological interest. We present numerical methods useful for modeling of these states. Their properties are governed by a Gaussian hypergeometric function, which cannot be reduced to either elementary or easily tractable functio... Title of program: MQSVIS Catalogue Id: AEMR_v1_0 Nature of problem Recently macroscopically populated quantum superpositions for light, generated by an optimal quantum cloner, were demonstrated. They are of fundamental and technological interest. Their properties are governed by Gaussian hypergeometric function 2 F 1 of half-integer parameters, which cannot be reduced to either elementary nor easily tractable functions. Computation of photon number distribution, visibility and mean number of photons, necessary for characterization of these states, requires eval ...
