    "abstract": "We analyse the effects of intrinsic decoherence on the probability of\ngenerating a tripartite GHZ state using a cool trapped ion coupled to a single\nmode of the cavity field and interacting with a resonant laser field. Milburn\nequation is solved for this tripartite system to obtain the time evolution of\ndensity matrix as a function of cavity-ion coupling, laser-ion coupling, and\nthe size of unitary time step relative to the time scale determined by system\nparameters. Starting with the system prepared initially in a separable state,\ndensity matrix is used to calculate the probability of tripartite GHZ state\ngeneration using coupling strengths reported in a recent experiment.",
