Estimation of teleported and gained parameters in a non-inertial frame
  We estimate the teleported and the gained parameters by means of Fisher information in a non-inertial frame. The sender and the receiver share an accelerated maximum or partial entangled state. The estimation degree of these parameters depends on Unruh acceleration, the used single mode approximation(within/ beyond), the structure of the initial teleported state, and the entanglement of the initial communication channel. The maximization and minimization estimation degree of the teleported parameters depend on the initial encoded information. The estimation degree of the parameters can be maximized if the partners teleport classical information.
