We provide the first proof-of-principle experimental implementation of certified qubit transmission through an untrusted quantum channel, using one part of a maximally-entangled photon as a probe. The theoretical framework includes self-testing in a non-IID and semi device-independent setting, combined with new results on lossy quantum channels.
