Abstract

Abstract: The tripartite entanglement changing with the observer’s acceleration is investigated. It is found that the entanglement decreases with increasing of acceleration. π-tangle decreases most quickly when three observers are all accelerating. The distribution of quantum information is discussed. It’s found that the entanglement and mutual-information can be redistributed, and they can reach the physical inaccessible region. The fidelity under the relativistic effect decreases with increasing of the observer’s acceleration, which indicates that the entanglement and fidelity are related to a certain extent.

Key words: non-inertial frames; tripartite entanglement; mutual-information; fidelity
