# Long distance entanglement and high-dimensional quantum teleportation in the Fermi–Hubbard model

Sanaa Abaach, Zakaria Mzaouali, and Morad El Baz

This repository is dedicated to the research on [Long distance entanglement and high-dimensional quantum teleportation in the Fermi–Hubbard model](https://www.nature.com/articles/s41598-023-28180-4). The primary focus is on the peculiarities of the Fermi-Hubbard model's ground state and its capability to sustain maximum long-distance entanglement, thus functioning as a quantum resource for high fidelity quantum teleportation over long distances.

# Main results



Ground State Entanglement: Analysis of the ground state of the Fermi-Hubbard model for optimal long-distance entanglement.


Scalability and Stability: Determination of the physical properties required for scalable entanglement and its stability analysis under Coulomb interaction and hopping amplitude variations.


Teleportation Fidelity: Investigation of how the selection of measurement bases influences the fidelity of quantum teleportation.


Hubbard Projective Measurements: Argumentation for the selection of an adequate measurement basis that aligns with the characteristics of the quantum channel to achieve perfect information transfer.
