  In this work we provide a genuine relativistic quantum teleportation protocol
whose classical communication component makes use of relativistic causal
propagation of a quantum field. Consequently, the quantum teleportation is
fully relativistic by construction. Our scheme is based on Unruh-DeWitt qubit
detector model, where the quantum state being teleported is associated to an
actual qubit rather than a field mode considered by Alsing and Milburn [PRL 91,
180404 (2003)]. We show that the existing works in (relativistic) quantum
information, including good definitions of one-shot and asymptotic channel
capacities, as well as algebraic formulation of quantum field theory, already
provide us with all the necessary ingredients to construct fundamentally
relativistic teleportation protocol in relatively straightforward manner.
