Abstract

The four quantum noises Bit Flip, Phase Flip, Depolarization, and Amplitude Damping as well as any potential combinations of them are examined in this papers investigation of quantum teleportation using qutrit states. Among the above mentioned noises, we observed phase flip has highest fidelity. Compared to uncorrelated Amplitude Damping, we find that correlated Amplitude Damping performs two times better. Finally, we agreed that, for better fidelity, it is preferable to provide the same noise in channel state if noise is unavoidable.
