Tripartite quantum teleportation in de Sitter spacetime
In this paper, a tripartite quantum teleportation scheme in de Sitter vacuum is constructed. Then we investigate the influence of vacuum fluctuation, temperature and two-atom distance on performance of the tripartite quantum teleportation. It is found that fidelity drops fast with temperature and evolution time increasing. While temperature is low relatively, the influence of two-atom distance cannot be negligible, the change of fidelity is different with two-atom separation and time varying. The results may be helpful for dealing with quantum information tasks in curve spacetime and exploring the properties of curve spacetime through quantum information means.
