Quantum Teleportation via Qutrit Entangled State

Abstract

Quantum entanglement is currently seen to be a resource that may be created, concentrated when needed, transported, and consumed. In quantum information processing, three-level quantum systems (qutrits) provide more advantages than qubits, such as higher security and resistance to noise. This work considers Unknown qubit and qutrit states may be teleported over a two-qutrit maximally entangled pair. as a quantum channel with less resource requirements than current protocols based on three-particle entanglement. The scheme presented here designs special measurement bases to realize faithful teleportation. In qubit teleportation, the protocol involves six measurement outcomes, each of which specifies a different unitary transformation for state recovery. Nine measurement bases are used in qutrit teleportation, with corresponding unitary operations to retrieve the initial state. The results demonstrate that a two-qutrit entangled state is sufficient to teleport the states of qubits and qutrits, being an economic resource with three-particle GHZ states. The novelty is the less entanglement resource and the straightforward building of measurement and unitary operations for high-dimensional systems. The paper illustrates the feasibility of qutrit teleportation and indicates the need for studying qutrit applications and experimental implementations.
