Query: Usefulness classes of travelling entangled channels in noninertial
  frames   The dynamics of a general two qubits system in noninetrial frame is
investigated analytically, where it is assumed that both of its subsystems are
differently accelerated. Two classes of initial travelling states are
considered:self transposed and a generic pure states. The entanglement
contained in all possible generated entangled channels between the qubits and
their Anti-qubits is quantified. The usefulness of the travelling channels as
quantum channels to perform quantum teleportation is investigated. For the self
transposed classes, we show that the generalized Werner state is the most
robust class. We show that starting from a class of pure state, one can
generate entangled channels more robust than self transposed classes.
