Quantum Teleportation without Irreversible Detection: NMR-Experiment

Abstract

We implement a quantum teleportation algorithm in NMR with ¹³C-labeled L-alanine. Here three ¹³C-nuclear spins are qubits and H-nuclear spins are employed as a well-defined quantum mechanical interface to a detector. Our experiment is considered as a realization of “quantum teleportation without irreversible detection” and is helpful for understanding the principle of quantum teleportation.
