We report the experimental demonstration of quantum teleportation of the quadrature amplitudes of a light field. Our experiment was stably locked for long periods, and was analyzed in terms of fidelity F and with signal transfer T-q=T++T- and noise correlation V-q=Vinparallel to out+Vinparallel to out-. We observed an optimum fidelity of 0.64+/-0.02, T-q=1.06+/-0.02, and V-q=0.96+/-0.10. We discuss the significance of both T-q>1 and V-q<1 and their relation to the teleportation no-cloning limit.

- Quantum interface between light and atomic ensembles (2008, background): “In the context of teleportation of coherent states, the question of the ”right” figure of merit was subject to considerable debate in the literature, see Bowen et al. (2003b); Braunstein et al. (2001); Grosshans and Grangier (2001); Ralph and Lam (1998) and references therein.”
