文摘

Generation of squeezed Schrödinger kitten state in a qubit&ndash;oscillator system. Evolution of quasiprobability distributions. Reconstruction of the oscillator states in the neighborhood of pure states. Non-Gaussian characteristics of the high entropy states. Hilbert&ndash;Schmidt distance as a faithful distinguisher between quantum states.
