N2 - Abstract- In this paper, the entanglement of different superpositions of photon added coherent states is investigated using concurrence criterion. The results show that as the difference between photons added in the two modes increases, the entanglement increases and the maximum entanglement occurs in negative superpositions. M3 ER -
