In this paper, we have studied the effect of one and two sided amplitude damping, phase damping and depolarization channel on Bell’s like state. We have found that these Bell’s like states have experienced exactly the same decoherence under all channels except two sided amplitude damping and one sided depolarization channel. In the case of two sided amplitude damping as well as one sided depolarization channel state │φ〉 =α│01〉+β│10〉 found more entangled compare to the state │ψ〉 = α│00〉+β│11〉,wich indicate that under the effect of these two damping channels, it is wise choice to use state │φ〉 =α│01〉+β│10〉.
