| An entangled quantum state is considered by applying a local photon excitation to each mode of an entangled coherent state. The entanglement property is investigated in terms of the entropy of entanglement. It is shown that applying a photon addition can improve the amount of entanglement. It is also examined that in a specific region of parameters, the state |ψ1-(α,m,n)> is least entangled when photon excitation is minimum. We study the statistical properties of such states by employing the quasi-probability functions. |
