Enhanced quantum teleportation in non-Markovian environments

TL;DR

This paper investigates how non-Markovian environments with memory effects can improve quantum teleportation fidelity, showing that such environments enable fidelity revival and enhancement over Markovian channels.

Contribution

It demonstrates that non-Markovian environments can enhance and revive quantum teleportation fidelity, offering a new approach to mitigate decoherence effects.

Findings

Fidelity is higher in non-Markovian channels compared to Markovian ones.

Memory effects cause revival of teleportation fidelity.

Non-Markovian environments improve overall teleportation quality.

Abstract

The protocol of the teleportation of an arbitrary unknown one-qubit state is investigated when the quantum channel is subject to the decoherence from the non-Markovian environments with the memory effects. The quality of the teleportation measured by the average fidelity and minimal fidelity can be enhanced in the non-Markovian channel. The memory effects give rise to the revival of the fidelity which is better than that obtained by the Markovian channel.
