Quantum teleportation of a single qutrit using two-qutrit entangled states

We demonstrate quantum teleportation of a qutrit system using a complete set of two-qutrit entangled states obtained from the representation theory of the SU(3) group. All measurement gates essential for end-to-end teleportation are systematically evaluated, and these are found to be nonunitary. Our approach extends Bennett’s teleportation protocol to the qutrit system with minimal modifications, preserving operational simplicity and underscoring the necessity of nonunitary measurement operators in high-dimensional systems.
