In this paper, the interaction between V-, lambda- and ladder-type trapped three-level ions with a two-mode quantized field is studied. Then, by solving the time-dependent Schrödinger equation for each of the mentioned trapped ions, the time evolution of entanglement between them and the quantized field is studied and compare with each other. Finally, by substituting three-level ions with two-level ones, we compare the entanglement between the two- and three-level trapped ions with the quantized field. It is concluded that in the same interaction condition, three-level trapped ions show more degrees of entanglement with the quantized field as compared with two-level ion.
