The distribution of orbital angular momentum (OAM) superposition mode before and after all-optical teleportation (AOT) when a ℓ = 1, b ℓ = 2, c ℓ = 3 and d ℓ = 4. The corresponding AOT fidelities are 0.63, 0.60, 0.56, 0.54, respectively. The bottom row in each subfigure shows the computer-generated hologram for OAM superposition mode and the corresponding images of input and output fields. The error bars are obtained from the standard deviations of multiple repeated measurements.
