Abstract

We suggest a self-testing teleportation configuration for photon qubits based on a Mach-Zehnder interferometer. That is, Bob can tell how well the input state has been teleported without knowing what that input state was. One could imagine building a ``locked'' teleporter based on this configuration. The analysis is performed for continuous variable teleportation but the arrangement could be applied equally to discrete manipulations.
