Experimental Realization of Teleporting an Unknown Pure Quantum State via Dual Classical and Einstein-Podolsky-Rosen Channels

TLDR

The study experimentally implements teleportation of unknown pure quantum states using quantum optics. The experiment uses a Bell measurement capable of distinguishing all four Bell states, enabling up to 100 % teleportation success. The results demonstrate full nonlocal teleportation of linearly and elliptically polarized states, matching Bennett’s scheme up to local operations and ruling out classical explanations.

Abstract

We report on a quantum optical experimental implementation of teleportation of unknown pure quantum states. This realizes all of the nonlocal aspects of the original scheme proposed by Bennett et al. and is equivalent to it up to a local operation. We exhibit results for the teleportation of a linearly polarized state and of an elliptically polarized state. We show that the experimental results cannot be explained in terms of a classical channel alone. The Bell measurement in our experiment can distinguish between all four Bell states simultaneously allowing, in the ideal case, a 100% success rate of teleportation.
