摘要
A pair of two level atoms A1A2, interacts with one of the two modes of squeezed field in an optical cavity while a third atomic qubit B interacts with the second mode in a remote cavity. We analyze the generation, sudden death and revival of tripartite entanglement as a function of initial conditions. A smaller squeezing of the field is needed to generate the same order of peak value W-type entanglement of remote atomic qubit with the pair A1A2 prepared initially in an entangled state as compared to the case when A1 and A2 are in a separable state at t = 0.
