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 Tₐ=T^++T^- and noise correlation Vₐ=V₈₍|₎ₔₓ^+V₈₍|₎ₔₓ^-. We observed an optimum fidelity of 0. 640. 02, Tₐ=1. 060. 02, and Vₐ=0. 960. 10. We discuss the significance of both Tₐ>1 and Vₐ<1 and their relation to the teleportation no-cloning limit.
Bowen et al. (Mon,) studied this question.
