  Permitting the transmission of unknown quantum states over long distances by
using entanglement, quantum teleportation serves as an important building block
for many quantum technologies. However, in the noisy intermediate-scale quantum
era, the practical realization of quantum teleportation is inevitably
challenged by the noise-induced decoherence. We here propose a noise-mitigation
mechanism applicable in both the discrete- and continuous-variable quantum
teleportation schemes. Via investigating the non-Markovian decoherence dynamics
of the two types of quantum teleportation schemes, we find that, as long as a
bound state is formed in the energy spectrum of the total system consisting of
the involved subsystems and their respective reservoirs, the quantum
superiority of the fidelity is persistently recovered. Supplying an insightful
understanding of the noise-mitigation protocols, our result paves the way to
the practical realization of noise-tolerant quantum teleportation.
