    "abstract": "We investigate the nonclassicality of photon-added coherent states in the\nphoton loss channel by exploring the entanglement potential and negative Wigner\ndistribution. The total negative probability defined by the absolute value of\nthe integral of the Wigner function over the negative distribution region\nreduces with the increase of decay time. The total negative probability and the\nentanglement potential of pure photon-added coherent states exhibit the similar\ndependence on the beam intensity. The reduce of the total negative probability\nis consistent with the behavior of entanglement potential for the dissipative\nsingle-photon-added coherent state at short decay times.",
