In this paper, some properties of multi-qubit states traveling innon-inertial frames are investigated, where we assume that all particles areaccelerated. These properties are including fidelities, capacities andentanglement of the accelerated channels for three different states, namely,Greeberger-Horne-Zeilinger (GHZ) state, GHZ-like state and W-state. It is shownhere that all these properties are decreased as the accelerations of the movingparticles are increased. The obtained results show that the GHZ-state is themost robust one comparing to the others, where the degradation rate is lessthan that for the other states particularly in the second Rindler region. Also,it is shown here that the entangled property doesn't change in the acceleratedframes. Additionally, the paper shows that the degree of entanglement decreasesas the accelerations of the particles increase in the first Rindler region.However in the second region, where all subsystems are disconnected at zeroacceleration, entangled channels are generated as the acceleration increases.Keywords: Multi-qubit states, Non-inertial frame, Fidelity, Capacity,Entanglement, GHZ state, GHZ-like state, W-state.
