Pairwise entanglement in the Heisenberg XX model with three-site interactions

► Thermal pairwise entanglement are dependent on the different types of three-site interactions and the magnetic field. ► The three-site interactions can enhance the thermal entanglement and improve the fidelity of the teleportation. ► The three-site interactions can weaken the destructive effect of the intrinsic decoherence to the entanglement evolution.
