Analysis of noisy channels in the simplified quantum teleportation protocol
Abstract
The standard quantum teleportation protocol inherently has problems, one of which is the disambiguation that restricts the safety and speed of quantum teleportation. Mastriani proposed a simplified protocol that eliminated the use of classical channels to avoid disambiguation when teleporting information. That being said, the quantum channels are still capable of being affected by noise which can lower the fidelity of the teleportation. In this paper, we studied the simplified protocol subjected to various noises, namely: bit flip, phase flip, depolarizing, and amplitude damping. The surface plot of fidelity showed that fidelity is at its maximum when the particles are maximally entangled, otherwise the value of fidelity decreases as the probability of noise increases. It is observed that the coefficients of the noisy quantum channel have an effect on the resulting fidelity.
