Optimal teleportation via a non-maximally entangled channel in qutrits system

Quantum teleportation provides a way to transmit information from one location to another via a quantum channel. In traditional teleportation schemes, if the quantum channel is a non-maximally entangled quantum state, the success probability of teleporting an unknown three-dimensional quantum state can not be reached 100%. Here we propose a deterministic teleportation scheme to overcome this challenge, and our results show that the success probability of teleporting a three-dimensional quantum state can be increased to 100%. In particular, we have analyzed the security of our teleportation process, including particle transmission, and proved this process safe. Our scheme has high experimental feasibility.
