Abstract Quantum-mechanical systems have information processing capabilities1, 2 that are not possible with classical devices. One example is quantum teleportation3, in which the quantum state of a system is transported from one location to another without moving through the intervening space. But although partial implementations4, 5 of quantum teleportation over macroscopic distances have been achieved using optical systems, the final stage of the teleportation procedure — which allows the complete recovery of the original state — was omitted. Here we report an experimental implementation of full quantum teleportation over interatomic distances using liquid-state nuclear magnetic resonance. We achieve teleportation of the quantum state of a carbon nucleus to a hydrogen nucleus in molecules of trichloroethylene, by exploiting natural phase decoherence of the carbon nuclei. Such a teleportation scheme may be used as a subroutine in larger quantum computations, or for quantum communication.
