Nonclassical properties of photon-added q-deformed cat states

摘要

The nonclassical properties of photon-added q-deformed cat states with q>1 is studied. The excitation number m has significant influence on their nonclassical properties. The squeezing effect of the photon-added q-deformed even cat state deepens with the increase of the excitation number m. The anti-bunching effect disappears faster with the increase of the excitation number m. The anti-bunching effect exists in the q-deformed photon-added odd and even cat states in a limited range, and disappears faster with the increase of the excitation number m.
