Abstract: The dynamics of an entangled state interacting with a single cavity mode is investigated in the presence of a random parameter. We show that the degree of entanglement decays with time and that the rate of decay is defined by features of a random parameter. Quantum teleportation through a dissipative channel and teleportation fidelity as a function of damping rates have been studied. The sensitivity of the fidelity with respect to the random parameter is discussed. We have evaluated the time interval during which one can perform quantum teleportation and send the information with reasonable fidelity for given values of the correlation length of the random parameter.
