Abstract
We show that the teleportation-based quantum state tomography (QST) protocol, originally built to reconstruct qubits (spin-1/2 systems), can be extended to deal with qutrits (spin-1 systems) as well. Similarly to the original proposal, only two resources are needed to implement the spin-1 teleportation-based QST protocol: (1) Alice should be able to implement the analog of Bell measurements for spin-1 systems; and (2) she should be able to prepare a few different single qutrit states that will be teleported to Bob.
