Quantum teleportation in three parties with an accelerated receiver

In the multi-party teleportation it is known that, in average, teleportation with W state is more robust than that with GHZ one. However if in the multi-party teleportation a receiver moves in an uniform acceleration, it is questionable that the superiority of W state would be still hold. In this article we consider the three-party teleportation with the receiver in an uniformly accelerated frame. We show that in general, the robustness of three-party teleportation depends on the acceleration of the receiver. Also we find that the fidelity of GHZ state depends on the angle of co-sender's single qubit measurement and the magnitude of acceleration. So we obtain the condition for the the angle of Bob's single qubit measurement and the magnitude of acceleration when the fidelity of GHZ state coincides with that of W one.
