WebTeleportation of masked information. In this contribution, we investigated the possibility of teleporting classical/quantum masked information, which may coded either in a single qubit or qutrit. For this purpose, different systems are used as quantum channels; two-qubit, three-qubit, two qutrit systems, and different protocols are applied.
