Abstract

Since the description of the quantum-mechanical state in phase space is not unique, a number of quasiprobabilities arise. Certain conditions are needed to determine the certainty of a nonclassical state. A squeezed coherent state can be approximately represented with reasonable accuracy by using quasiprobability functions based on multiple Schrodinger kittens. This technique features a quasiprobability function that exists everywhere after adding some infinitesimally small noise to the system.
