In this paper, we present a genuine relativistic quantum teleportation protocol that utilizes the relativistic causal propagation of a quantum field for classical communication. Based on the Unruh-DeWitt qubit detector model, we demonstrate that the existing works in (relativistic) quantum information provide all the necessary ingredients to construct a fundamentally relativistic teleportation protocol.
In this paper we provide a genuine relativistic quantum teleportation protocol the classical communication component of which makes use of relativistic causal propagation of a quantum field. Consequently, the quantum teleportation is fully relativistic by construction. Our scheme is based on the Unruh-DeWitt qubit detector model, where the quantum state being teleported is associated to an actual qubit rather than the field mode considered by Alsing and Milburn [P. M. Alsing and G. J. Milburn, Phys. Rev. Lett. 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 a fundamentally relativistic teleportation protocol in a relatively straightforward manner.
